Read each question carefully and follow the instructions to solve for the variable.

1. To isolate a variable, you need to perform the   operation to both sides of the equation.

2. In the equation x + 5 = 12, the variable is  .

3. If you have 3y = 21, you would   both sides by 3 to find the value of y.

4. Which operation would you use to isolate 'x' in the equation x - 7 = 15?

a

Add 7

b

Subtract 7

c

Multiply by 7

d

Divide by 7

5. What is the value of 'y' in the equation 4y = 32?

a

6

b

7

c

8

d

9

6. Solve for 'a': a + 12 = 30

7. Solve for 'b': b - 9 = 23

8. Solve for 'c': 6c = 48

9. Solve for 'd': d / 5 = 10

10. To solve for 'x' in x / 4 = 8, you should multiply both sides by 4.

T

True

F

False

11. The equation 2x + 3 = 7 requires two steps to isolate 'x'.

T

True

F

False

12. Solve for 'x': 2x + 5 = 17

13. Solve for 'y': 3y - 4 = 14
