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 x - 1= 12

x + 6 = 12 3x= 12 Goal: To get the variable by itself Rule: Whatever you do to one side, you have to do to the other! - 6 x 6 = ÷3 x = 4

Goal: To get the variable by itself Rule: Whatever you do to one side, you have to do to the other! x - 1= 12 ∙4 x48 = +1 x = 13

QUIZ – QUIZ - TRADE What operation is in the problem? What is the inverse?
