What property of inequality can justify the math in Step 2?
Step 1:
−6(3w−7)>−66
−18w+42>−66
Step 2:
−18w+42−42>−66−42
−18w>−108
Step 3:
−18w−18>−108−18
w<6

The property of inequality that justifies the math in Step 2 is the property of additive inverse. This property states that adding the additive inverse (or the negation) of a number to both sides of an inequality does not change the direction of the inequality.
