Answer 1

Division Property of Equality

Explanation:

yea

Answer 2

Division Property of Equality

Explanation:

from the second from last step, we have

2x = -36

if we divide both sides of the equation equally by 2, we get

(2x ) / 2 = (-36) / 2

x = -18 ..., which is exactly the last step that is given in the question

hence in order to get to the last step, we divide both sides of the equality by 2 (a non-zero number).

AKA "Division Property of Equality"
