  1. there is an app called photomath, it solves the math for you.
    (6y-30/(y-1)) * (5y-5/3y^2-15y)
    =(6(y-5))/(y-1) * (5(y-1))/(3y(y-5))
    =2*(5/y)
    =10/y

  2. There were two divisions, one by (y-1) , so y ≠ 1
    the other was (3y(y-5)) , so y ≠ 0, 5

    final answer would be
    = 10/y , y ≠ 0, 1, 5
