    Do you want me to explain it to you after I solve it? What part of the question do you need help on?

    \[\frac{ y }{ y^2-2y+1 }+\frac{ 6 }{ y^2+6y-7 }\]Is this the question?

    Okay here are the steps then:\[\frac{ y }{ (y-1)^2 }+\frac{ 6 }{ (y-1)(y+7) }\]

    Every time i deal with quotients adding together (even for fraction) i always abide by this rule: \(\LARGE \frac{A}{B}+\frac{C}{D}\) \(\Large\frac{A*D+C*B}{B*D}\)

    Next step:\[(y-1)(\frac{ y }{ (y-1)^2 }+\frac{ 6 }{ (y-1)(y+7) })\]

    That would be the sum. You can still go further if you are trying to solve for y.
