Equations and Inequalities

Which equation has x = 9 as a solution?

• 4 + x = 12
• 5x = 45
• 2x = 20
• x + 7 = 26

28 + v = 52

What could I do to both sides to get the variable by itself?

• Subtract 28

• Add 28

• Subtract 52

• Multiply by 28

14g = 84

Which inverse expression should be used to help solve for the variable?

• 14(84)

• 84 - 14

• 84 ÷ 14

• 14 ÷ 84
