  1. the LCD is 60, so multiply each term by 60

    300r + 90 = 180r - 720
    120r = -810
    r = -810/120 = -387/4

    If on the other hand, you meant

    (5r+30)/20 = (3r-36)/3
    then
    60r - 720 = 15r + 90
    45r = 810
    r = 18

    notice how important it is to put in brackets to establish the correct order of operation?
