Solving Multi-Step Equations

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

What is the error?

• Adding 2x to 3x

• Subtracting 5 from both sides

• Adding 2x to -2x

• Dividing by 5 on both sides

3(x-8)=3x-24

• No Solution

• x=3

Solve for x : 2x - 3 + 4x = 27

• x = 12

• x = 4

• x = 5

• x = 15

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

• x = 4

• x = 3

• x = 2

• x = 1
