x/5 - x/11 = 60
x[(1/5)-(1/11)] = 60
x = 60 / [(1/5)-(1/11)]
x = 60 / [(11/55) - (5/55)]
x = 60 / [6/55]
x = 60 * (55/6)
x = 10 * 55
x = 550
x[(1/5)-(1/11)] = 60
x = 60 / [(1/5)-(1/11)]
x = 60 / [(11/55) - (5/55)]
x = 60 / [6/55]
x = 60 * (55/6)
x = 10 * 55

x/5 - x/11 = 60
11(x/5) - 5(x/11) = 60
(11x - 5x) / 55 = 60
6x = 3300
x = 550
11(x/5) - 5(x/11) = 60
(11x - 5x) / 55 = 60
