i factor out a negative one from (5-y) to make it same like (y-5)

i cancel off y-5's. and i get


but the real answer have to be 3+y/1-3y what i doing wrong?

  • math-calculus -

    Did you know that -3/4 = 3/-4 = -(3/4)
    they are all the same
    so look at your answer, which is correct

    = (3+y)/(-1(3y-1))
    = (3+y)/(1-3y)

    Sometimes it happens that you have an answer that looks different from the one in your text, but you may still be correct.
    I would have marked your answer as correct to get full marks.

    oh wow i had not know that thanks so much Reiny for telling and explaining to me :)
