Review for Equations

Translate the following into an equation. The difference of a number, x, and 7 is 15

• x - 7 = 15
• x + 7 = 15
• 7x = 15
• x/7 = 15

Match the equation to a step that will help solve the equation for x.
5x = 0.4

• Divide by 5
• Divide by -5
• Subtract by 5
• Add by 5

Solve the equation below:

• k = 152
• k = 176
• k = 5
• k = 27

Solve for x:
-30 - 5x = 120

• x = 18
• x = -18
• x = 30
• x = -30

Use the Distributive Property:
5(2x - 3)

• 10x - 15
• 10x - 3
• 7x - 8
• 2x + 2

4(x+8)=44

• x=-3
• x=12
• x=11
• x=3
