One-Step Equations and Inequalities

Solve for the variable.
x - 5 = 20

• x = -25

• x = -15

• x = 15

• x = 25

What is the correct step to solve this equation?
m + 4 = 10

• add 4 to both sides

• add 10 to both sides

• subtract 4 from both sides

• subtract 10 from both sides

What is the correct step to solve for the variable?
15 = m - 5

• add 15 to both sides

• add 5 to both sides

• subtract 15 from both sides

• subtract 5 from both sides
