Which equation has x = 2 as a solution?

• 3 + x = 10
• 11 + x = 13
• 4x = 32
• 5x =25

What is the first step to solve this equation:

- 3x -11 = 44

• Add 3 to both sides

• Subtract 11 from both sides

• Add 11 to both sides

• Divide 3 on both sides.

What operation would you perform first and then second when solving for m in the following equation?

10 + 7m = 17

• subtract 10, divide by 7

• divide by 7, subtract 10

• multiply by 7, add 10

• add 10, multiply by 7

4 + 7a + 6 - 2a = 45

• a = 5

• a = 8

• a = - 4

• a = 7

-9(w - 4) = 54

• w = 10

• w = -6

• w = -3

• w = -2

6p + 10 - 3p = 37

• p = 9

• p = -5

• p = 7

• p = 8
