Solving Multi Step Equations Review

Solve for b:
 3(b - 4) = -3

• b = 3

• b = -3

• b = 5

• b = -5

Solve for x:

2x - 3 + 4x = 27

• x = 12

• x = 4

• x = 5

• x = 15

Solve for x:

4x + 20 - 2 = 60 + 2x

• 21

• 39

• 7

• -7

Solve for x:

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

• x = 5/3

• x = 3

• x = 1

• x = 2

Solve the equation:
3x - x + 2 = 4(2x - 1)

• x = 0

• x = 1

• x = -1

• x = -2

Solve for x:

-4x + 1 = 21

• x = 120

• x = 5

• x = 30

• x = -5

When solving equations, sometimes you have to simplify the equation first. When solving 6x + 5 + 2x - 8 = 40, what might your first step look like?

• 4x + 13 = 40

• 4x - 3 = 40

• 8x + 13 = 40

• 8x - 3 = 40

5x - 21 - x = x -18

• 1

• -1

• 13

• -13

3x + 21 - 91 = -3x + 5x - 50

• 20

• 72

• 4

• -72

What is the first step in solving the equation 2a - 4(a - 5) = 10

• Add 4 to both sides

• Add the 2a and a 

• Distribute 4 to a and -5

• Distribute -4 to a and -5
