Solving Multi-Step Equations

Solve:

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

• 1.2
• 6
• -6
• 7.5

8v - 4(v + 8) = 8

• 2
• 10
• 4
• -4 

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

Solve: 7x = 3x + 24

• 10

• 4

• 6

• 14

Solve: 10x + 9 = 4x - 9

• 3

• 0

• -18

• -3

Solve the equation: 4x - 5x + 9 = 5x - 9

• x=3

• x=-3

• x=-9

• x=9

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

• x=5/3

• x=3

• x=1

• x=2

Solve: 14p - 8 = 22 + 20p

• -5

• 5

• 30

The objective when solving an equation is to....
