Solving Multi-Step Equations

Solve:
3(3x - 6) = 18

• x = 4
• x = -4
• no solution
• infinite solutions

-15 = 5a +12- 2a + 6

• -11
• -3
• 10
• 7

3a + 9 + 4a = 2

• -1
• 1
• no solution
• -7

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

8v - 4(v + 8) = 8

• 2
• 10
• 4
• -4 

2x - 3 + 4x = 27

• 12
• 4
• 5
• 15

2x + 3(5x - 7) = 47

• 1
• 2
• 3
• 4

-11 + 3(b + 5) = 7

• 1
• -1
• 3
• -3

5x - 4 + 2x = 3

• 1
• 2
• 3
• 4

2x - 3 + 4x = 27

• 12

• 4

• 5

• 15
