Question

25= -7(y-3)+5y   Given
25= -7+21+5y    Distributive Property
25= -2+21  Substitution Property
4=-2y+21                   ?
-2=y             Division Property(=)

anonymous · Answer

for the substitution property where does the 5y go?

anonymous · Answer

well the question is asking what the step is after substitution

anonymous · Answer

I don't get it though... you have -7 then it becomes -2 and you lose 5y then suddenly a -2y comes out of no where.

anonymous · Answer

on the one with the questionmark after it, it should be 4=-2y

anonymous · Answer

there we go...then it's subtraction property of equality because we are subtracting 21 from each side

anonymous · Answer

so how does the problem even work I dont really understand the whole thing.... Like how do you get from the given to the answer?

anonymous · Answer

it's just like you were solving it, but they do the steps for you and you have to explain what they're doing.

anonymous · Answer

okay Thanks for the help! (:
