x - 62 = 123

How should you show your work to isolate (get alone) the variable and solve the equation?

• Add 62 to each side.

• Subtract 62 from each side.

• Multiply each side by 62.

• Add 123 to each side.

-5 + m = 15

What inverse operation would you

do to isolate the variable above?

• Add -5 to both sides

• Add 5 to both sides

• Subtract 5 to both sides

• Divide by -5 to both sides

6n = 24

What inverse operation would you do to isolate the variable above?

• Multiply by both sides by -6

• Divide both sides by -6

x - 8 = -5

What needs to be done to both sides?

• subtract 8

• add 8

• 3

• add 5

20 = x + 12

What operation should be done to both sides?

• Add 12

• Subtract 12

• x = 8

• subtract 20

The objective (goal) when solving an equation is to....
