penyelesaian dari sistem persamaan 2/x - 1/y = 7/5 dan 1/x + 3/y = 14/15 adalah?

2/x -1/y = 7/5...(1)
1/x + 3/y = 14/15...(2)
eliminasi 2/x, maka (2)×2
2/x + 6/y = 28/15
2/x -1/y = 7/5
------------------- -
7/y = 7/15
y = 15
eliminasi 3/y, maka (1)×3
6/x -3/y = 21/5
1/x +3/y = 14/15
-------------------- +
7/x = 35/15
7/x = 7/5
x = 5
HP = { ( 5, 15 ) }
