Justify each step with a property of algebra, put the correct property for each equation 5(2y−3)−4y=8−2y−15(what’s the property of this?)
5(2y−3)−4y=−2y−7(what’s the property of this?)
5(2y−3)=2y−7 (what’s the property of this?)
10y−15=2y−7 (what’s the property of this?)
8y=8 (what’s the property of this?)
y=1 (what’s the property of this?)

step-by-step explanation:

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.

yes

step-by-step explanation:

they have to be opposite and reciprocal of eachother.
