Solve: 10x + 9 = 4x - 9

• 3

• 0

• -18

• -3

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

• x=5/3

• x=3

• x=1

• x=2

What is the FIRST step to solving this equation?

-11 - 3x = 44 - 2x

• Combine like terms

• Get the variable on one side

• Distribute

• Solve using inverse operations

What is the first step you should take to solve this problem?

1 + 4n - 6n = 1 - 8n

• subtract 8n to both sides

• multiply 6n to both sides

• combine the like terms 4n + -6n

Solve.

Translate into an equation. Do not solve.

You bought one magazine for $5 and four erasers. You spent a total of $29. How much did each eraser cost?

• 5x + 4 = 29

• 4x + 5 = 29

• 5x - 4 = 29

• 4x - 5 = 29
