Solving Multi-Step Equations

Solve the equation:
3(x - 1) = 2x + 9

• x = 12

• no solution

• x = 10

• x = 6

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

• infinite solutions

• x = 1

• x = -1

• no solution

2x - 3 + 4x = 27

• 12

• 4

• 5

• 15

33 = 4a - 7

• a=-10

• a=10

• a=4.5

^{(a + 3)}⁄₇ = 3

• a= 18

• a= 21

• a= 4

• a= 11

8v - 4(v + 8) = 8

• 2

• 10

• 4

• -4 

What is the first step to solve this equation:
11 - 3x = 44

• Add 3 to both sides

• Subtract 11 from both sides

• Add 11 to both sides

• Divide 3 on both sides.

Bob has $150 in his savings account and saves $40 per month. Which of the following equations would be accurate if Bob has saved $400?

• 400 = 150 + 40

• 400 = 150 + 40x

• 400 = 150x + 40

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
