%283%2F5%29x%2B%281%2F12%29y=24
Multiply by 60.
1.36x%2B5y=1440
.
.
.
%281%2F9%29x-%282%2F9%29y=13
Multiply by 9
2.x-2y=117
Multiply eq. 1 by 2 and eq. 2 by 5 and add them together.
72x%2B10y%2B5x-10y=2880%2B585
77x=3465
highlight%28x=45%29
.
.
Then from eq. 2,
45-2y=117
-2y=72
highlight%28y=-36%29
