Equations Inequalities Study Guide

Solve:
3x + 7 = -8

• 5
• -5
• -12
• -18

What is the first step to solve this equation:
11 - 3x = 44

• Add 3 to both sides
• Subtract 11 from both sides
• Add 11 to both sides
• Divide 3 on both sides.

9c-3c=48

• c=9
• c=3
• c=4
• c=8

 What is the second step in solving the following equation?
-3x + 5 = 20

• Subtract 5 from both sides
• Divide both sides by -3
• Divide both sides by 3
• add 3x to both sides

Solve for v.

• 60
• -3
• 15
• 3

Solve for x.

• 55
• 60
• 15
• 35

Translate: 
Four times a number plus six IS 30.

• 4 + 6 = 30
• 4x + 6 = 30
• x + 4 times 6 = 30
• 30 = 4x

Solve the inequality.
x + 5 ≤ 13

• x ≥ 8
• x ≥ 18
• x ≤ 8 
• x ≤ 18 

When you graph an inequality, you used a closed dot when you use which symbols?

• x is less than or equal to -2
• x < -2
• -2 < x
• x is greater than -2
