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
