    Given x= (y-5)/(y+2), express y in terms of x

    x= (y-5)/(y+2)

    How do I express y in terms of x?

    Attempt:

    x(y+2)= y-5
    xy+2x = y-5
    y=xy +2x +5

    But this is not the correct answer.

    xy+2x = y-5
    Move all terms containing y to one side. Next, think 'factoring'.

    Ah yes, factoring was indeed the key, I have solved this.
