Model One Step Equations Addition and Subtraction

Solve for x

• x = 4

• x = 1

• 2x = 4

• x = 2

To solve one-step equations, you have to use the ________________ operation.

• Integer

• Inverse

• Additive

• Subtractive

What would be the best first step to solving the equation?
-3=x+5

• add 3 to both sides

• subtract 5 from both sides

• add 5 to both sides

• subtract -5 from both sides

-22 + x = -42

• 64

• -64

• 20

• -20

12 = x - (-18)

• 6

• -6

• 30

• -30

Solve the equation:
-5x = 25

• x = 20

• x = -20

• x = -5

• x = 5

2 + n =16

• 18

• -18

• 14

• -14

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

• add 5 to both sides

• add 15 to both sides

• subtract 15 from both sides

• subtract 5 from both sides

x - (-2) = 7

• -9

• -5

• 5

• 9

What what is the inverse operation of subtraction?
