Solve: 5x + 15 = 10x - 40

• x = 10

• x = -10

• x = 11

• x = -11

Solve: 9x + 1 = 64

• x = 6

• x = 7

• x = 8

• x = 9

Solve: -2x + 18 = 2x + 40

• x = -5.5

• x = 6.5

• x = -4.5

• x = 5.5

Solve: 4x - 3 = 6x - 19

• x = -8

• x = 11

• x = -11

• x = 8

Solve:
2(4x-3) - 8 = 4 + 2x

• x = 5/3
• x = 3
• x = 1

Solve:
5y + 34 = -2(-7y+1)

• y = -4
• y = 9
• y = 4
• y = 36/19

What is the first step you should take to solve this problem?

-3(x - 2) = -8 +9b

• add 8 to both sides

• subtract 9b from both sides

• Distribute -3 to the x and -2

• add 2 to both sides
