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

• A
• B
• C
• D

Solve.
(2x - 3) / 4  = 9

• x = 24
• x = 12
• x = 17.5
• x = 19.5

Which step cannot be performed first when solving the equation

5 - 2(x - 7) = x + 1 + 3x

• Distributing -2 to (x - 7)

• Combining x and 3x

• 5 - 2

is 7 a solution to the equation
3x+8-x=5x-4

• yes
• no
• maybe

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

• Add 4 to both sides
