4-9 Solving Multi-Step Equations

What is the first step to solve the equation?

5(x-2) = 20

• use the distributive property

• combine like terms

• divide both sides by 5

• add 2 to both sides

-4(y+7) = 24

• y = -13

• y = 13

• y = -1

• y = 28

16 = 4(x-5)

• y = 3

• y = 9

• y = 27

• y = 36

What is the first step to solve the equation?

36 = 8n + n

• combine like terms

• subtract 8n on both sides

• divide 9 from both sides

• n = 4

Solve for n

5n + 3n = 32

• n = 8

• n = 32

• 8n = 32

• n = 4

Solve for j

120 = 9j + 6j

• j = 15

• 120 = 16j

• j = 8

• 120 = j

Solve for x

x + 5 = 10

• x = 15

• x = 5

• x = 2

• x = 0

3x + 5 = 20

• x = 15

• x = 28

• x = 8

• x = 5

Solve for q

15q - 18q - 12 = 9

• q = 7

• q = -7

• q = -3

• q = 15

n(2 + 2) = 16

• n = 2

• n = 4

• n = 8

• n = 1
