SOLVING ONE STEP EQUATIONS

THINK – PAIR - SHARE

• Think: What does the word inverse mean?•Pair•Share

INVERSE OPERATIONS

• Operations that “undo” each other

HOW DOES THIS HELP US SOLVE ONE STEP EQUATIONS?

• What operation is in the problem?• What is the inverse operation?

x + 6 = 12

3x= 12

= 12 x - 1= 12

x + 6 = 12 3x= 12

Goal: To get the variable by itselfRule: Whatever you do to one side, you have to do to the other!

- 6

- 6x 6

=

÷3

÷3x

= 4

Goal: To get the variable by itselfRule: Whatever you do to one side, you have to do to the other!

= 12x - 1=

12∙4 ∙4x 4

8 =

+1

+1x

= 13
