-5(3x + 5) = -10x + 20  is problem also @koymoi

anonymous · Answer

-5(3x + 5) = -10x + 20
-15x - 25 = -10x + 20
-15x -25+25 = -10x + 20 + 25
-15x = -10x + 45
-15x + 10x = -10x + 10x + 45
-5x = 45
-5x/-5 = 45/-5
x = -9
I think

@koymoi  and @LoveYou*69  I would like to see you not just give the answer basically. Let the OP do the actual work. Let the OP think and let you see what step is next. Ask the OP questions and explain what you are doing please. :D

I agree, doing all the algebraic steps for a person is not going to help them on a test.
