    635/72=-5/2 (-11/4+x)

    distribute

    635/72 = - 5/2 * - 11/4 - 5/2x

    635/72 = 55/8 - 5/2 x

    multiply each side by 72 to clear the fractions

    72*635/72 = 72 * (55/8 - 5/2 x)

    distribute

    635 = 72 * 55/8 - 72 * 5/2 x

    635 = 495 - 180x

    subtract 495 from each side

    140 = - 180 x

    divide by - 180

    -140/180 = x

    -14/18 = x

    -7/9 = x
