    x*y-5=k

    add 5 to both sides

    x*y=k+5

    divide x by both sides

    y=(k+5)/(x)

    xy - 5 = k

    Add 5 to both sides: xy -5 (+5) = k + 5

    Now you have: xy = k + 5

    Divide both sides by x: xy/x = (k+5)/x

    This gives you:

    y = (k + 5) over x

    Source(s): My vague recollection of high school math. Which means I could totally be wrong, btw. Edit: Nvm, it is indeed correct.
