Multi Step Equation Practice

2x - 3 + 4x = 27

• x = 12
• x = 4
• x = 5
• x = 15

Which step cannot be performed first in order to solve the equation?
6x + 2x - 3(x + 1) - 5 = 27

• Add 6x + 2x
• Subtract 1 from both sides
• Add 5 to both sides
• Distribute -3

18 = 3(3x-6)

• x = 4
• x = 1/44
• x = - 44
• x = - 4

5x - 4 + 2x = 3

• 1
• 2
• 3
• 4

-11 + 3(b + 5) = 7

• b = 1
• b = -1
• b = 3
• b = -3
