    r = (-3y - 2k)/(a - 1)

    2k + ar = r - 3y

    Try different ways to find the value of r. Isolating r variables is the better way to solve for r.

    ar = r - 3y - 2k

    ar - r = -3y - 2k

    Factor the left side.

    r(a - 1) = -3y - 2k

    r = (-3y - 2k)/(a - 1)

    r= 2k+3y/1-a

    2k + 3y = r - ar

    2k + 3y = r( 1 - a)

    r = (2k + 3y) / ( 1 - a)
