2x - 6 = -24

​STEPS

1) Add or Subtract to remove a number

Manipulate the equation to get the variable by itself

2) Multiply or Divide to remove a number

Match

Match the following equation with the first step you would perform to solve.

• 5x - 3 = 21

• 5x + 3 = 1

• 3x + 5 = 6

• 3x - 5 = 9

add 3 to both sides

subtract 3 from both sides

subtract 5 from both sides

add 5 to both sides

• add 3 to both sides

• subtract 3 from both sides

• subtract 5 from both sides

• add 5 to both sides

2) Multiply or Divide to remove a number

Match

Match the following equation with the first step you would perform to solve.

• -6 + 3x = 14

• 6 - 3x = 16

• 3 - 6x = 2

• -3 - 6x = 19

add 6 to both sides

subtract 6 from both sides

subtract 3 from both sides

add 3 to both sides

• add 6 to both sides

• subtract 6 from both sides

• subtract 3 from both sides

• add 3 to both sides

Math Response

-3 = 15 - 9x

​STEPS

1) Add or Subtract to remove a number

EXAMPLE

2) Multiply or Divide to remove a number

Match

Match the following equation with the first step you would perform to solve.

• 12 = -4 - 7x

• 12 = 4 + 7x

• 12 = 7 - 4x

• 12 = -7 + 4x

add 4 to both sides

subtract 4 from both sides

subtract 7 from both sides

add 7 to both sides

• add 4 to both sides

• subtract 4 from both sides

• subtract 7 from both sides

• add 7 to both sides
