Multiply the first equation by 240,
15x%2B16y=108
Multiply the second equation by 540,
27x-20y=48
Multiply the first equation by 5 and the second equation by 4 and add them,
75x%2B80y%2B108x-80y=540%2B192
183x=732
x=4
Then use either equation to solve for y.
60%2B16y=108
16y=48%7D%7D%0D%0A%7B%7B%7By=3
(4,3)
