Keep rolling with Inverse Operations.

Examples: 2 Step

A. 3x - 7 = 11 Step 1 add 7 + 11 = 18
3x = 18 Step 2 divide 18/3 = 6

B. 4y + 3 = 15 Step 1 subtract 15 - 3 = 12
4y = 12 Step 2 divide 12/4 = 3

C. X/2 -4 = 6 Step 1 add 4 + 6 = 10
X/2 = 10 Step 2 multiply 210 = 20

D. Y/3 + 5 = 10 Step 1 subtract 10 - 5 = 5
Y/3 = 5 Step 2 multiply 35 = 15

WORK:
1. 3x - 5 = 14

2. 4y + 6 = 30

3. X/2 - 8 = 6

4. Y/7 + 8 = 3

5. 7y + 12 = 47

6. X - 11 = 14

7. Y/6 - 4 = 6

8. 4x = - 28

9. 9y + 13 = 49

10. 2x = -10
