Solve:

2(2x + 3) = -6(x + 9)

• 2

• 6

• -6

• 7.5

Solve:

7x + 19 = -2x + 55

• 4

• 14.8

• 8.2

• -4

Solve for x:

2 ( x + 5 ) - 7 = 3 ( x - 2 )

• x = 6

• x = -14

• x = 9

• x = 28

Solve for x:

3 ( x + 1 ) - 5 = 5x -2

• x = -1

• x = 0

• x = -2

• x = 1

What is the first step to solve this equation? 2x + 3(5x - 7) = 47

• Add 7 to both sides

• Combine 2x and 5x

• Distribute the 3 to 5x and - 7

• Subtract 2x from 5x
