LINEAR EQUATIONS IN 1 VARIABLE TYPE 1 GAME (A)
Linear equations in 1 variable single step addition or subtraction operation
Linear equations in 1 variable single step addition or subtraction operation
Q. Solve to find the value of the variable: x - 7 = 14
Q. Solve to find the value of the variable: x - 7 = 14
Q.
Let us leave ‘x’ here on Left Hand Side
&
send number ‘-7’ to the other side.
‘-7’ or ‘7’ is connected to ‘x’ by subtraction operation
∴ Change sign & send to other side. ⇒ -7 → +7 (changed sign)
We need the variable ‘x’ on one side & number values on another side.
⇒ x = 14 + 7
⇒ x = 21
Value of variable ‘x’ is 21.
(we write the previous resident ‘14’ first on the right hand side)

Q. Solve to find the value of the variable: y + 9 = 13
Q. Solve to find the value of the variable: y + 9 = 13
Q.
Keep variable on Left Hand Side (LHS)
Aim is to keep variable ‘y’ on one side and number values to the other side.
Take ‘+9’ or ‘9’ to right hand side (R.H.S)
⇒ y = 13 - 9
⇒ y = 4
Value of variable ‘y’ is 4.
(we respect the previous resident ‘13’ and write it first)
Now, how is ‘9’ connected to the rest of the expression on Left Hand Side?
By addition operation
∴ change sign & send to other side ∴ +9 → -9

Q. Solve to find the value of the variable: x - 7 = 10
Q. Solve to find the value of the variable: x - 7 = 10
Q.
Let ‘x’ be on Left Hand Side itself.
Let us send ‘-7’ or ‘7’ to the right hand side.
Aim is to keep variable ‘x’ on one side and number values on another side.
⇒ x = 10 + 7
⇒ x = 17
Value of ‘x’ is 17.
(But we first respect & write the previous resident ‘10’ first)
Now, how is ‘-7’ connected to the rest of the expression on the Left Hand Side?
By subtraction operation
⇒ Change sign & send to the other side ∴ -7 → +7

Q. Solve to find the value of the variable: +11 + x = 19
Q. Solve to find the value of the variable: +11 + x = 19
Q.
Send ‘11’ to the right hand side.
Let us keep variable ‘x’ on Left Hand Side
Aim is to keep variable ‘x’ on one side and number values on the other side.
⇒ x = 19 - 11
⇒ x = 8
∴ Value of variable ‘x’ is 8.
(We respect the previous resident on the right hand side ‘19’ and write it first)
Now, how is ‘11’ connected to the rest of the expression on the LEFT side?
By addition operation
∴ Change sign & send to other side. ⇒ +11 → -11 (Sign of 11 is changed)

Q. Solve to find the value of the variable: x - 5 = 7
Q. Solve to find the value of the variable: x - 5 = 7
Q.
Let us keep ‘x’ variable on one side.
Let us send ‘-5’ to other side
Aim is to keep variable on one side (i.e: ‘x’) and numeric values on the other side.
⇒ x = 7 + 5
⇒ x = 12
∴ Value of x is 12.
(We first respect & write the previous resident ‘7’ first)
Now, How is ‘5’ connected to the rest of the expression on the Left Hand Side?
By subtraction operation
∴ Change sign of ‘5’ & send to other side
⇒ -5 → +5 (Sign of 5 is changed)

Q. Solve to find the value of the variable: 8 + x = 3
Q. Solve to find the value of the variable: 8 + x = 3
Q.
Let us send 8 to the other side.
Let ‘x’ variable be on Left Hand Side.
Aim is to keep variable ‘x’ on one side and send numerical values to the other side.
⇒ x = 3 - 8
⇒ x = -5
∴ Value of ‘x’ variable is ‘-5’
(We first respect the previous resident ‘3’ & write it first)
Now, how is ‘8’ connected to rest of the expression on the Left hand side?
By addition operation
∴ Change sign & send to other side
∴ +8 → -8
(Sign of 8 is changed)

Q. Solve to find the value of the variable: x - 4 = 5
Q. Solve to find the value of the variable: x - 4 = 5
Q.
Let us keep ‘x’ on one side (Left hand side)
Let us send ‘-4’ to the other side (Right hand Side)
Aim is to keep the variable ‘x’ on one side and the numeric values on the other side.
⇒ x = 5 + 4
⇒ x = 9
∴ Value of variable ‘x’ is found to be 9.
(We respect the previous resident ‘5’ and write it first)
Now, how is ‘4’ connected to the rest of the expression on the left hand side?
By subtraction operation
∴ Change sign & send to other side. ⇒ -4 → +4
(Changed sign of 4)

Q. Solve to find the value of the variable: x + 5 = 12
Q. Solve to find the value of the variable: x + 5 = 12
Q.
Let us keep ‘x’ variable on Left Hand Side
Let us send ‘+5’ to the Right Hand Side
Aim is to keep variable ‘x’ on one side and send number values to another side.
⇒ x = 12 - 5
⇒ x = 7
∴ Value of variable ‘x’ is found to be 7.
(We first write the previous resident of Right hand Side out of respect)
Now, How is ‘5’ connected to the rest of the expression on the Left Hand Side?
By addition operation
∴ Change sign & send to other side ⇒ +5 → -5
(Sign of 5 has been changed)

Q. Solve to find the value of the variable: x + 3 = -2
Q. Solve to find the value of the variable: x + 3 = -2
Q.
keep ‘x’ variable on Left Hand Side
Send ‘+3’ to the right hand side
Aim is to keep variable ‘x’ on one side and send numeric values to another side.
⇒ x = -2 - 3
⇒ x = -5
∴ Variable x is found to be ‘-5’
(We write the previous resident ‘-2’ first, out of respect)
Now, How is ‘+3’ connected to the rest of the expression on the left hand side?
By addition operation
∴ Change sign & send to other side ⇒ +3 → -3
(Changed the sign of 3)

Q. Solve to find the value of the variable: x - 7 = 6
Q. Solve to find the value of the variable: x - 7 = 6
Q.
Keep ‘x’ variable on Left Side.
Send ‘(-7)’ to the Right hand Side
Aim is to keep the variable ‘x’ on one side and send numeric values to another side.
⇒ x = 6 + 7
⇒ x = 13
∴ Value of ‘x’ variable is found to be 13.
(We first write the previous resident ‘6’ out of respect)
Now, How is ‘7’ connected to the rest of the expression on the Left Hand Side?
