3x + 2y - 10 = 0
3x + 2y = 10
2x + 3y - 9 = 0
2x + 3y = 9
3x + 2y = 10 (x2)
2x + 3y = 9 (x3)
--------------------------
6x + 4y = 20
6x + 9y = 27
------------------------- -
-5y = -7
y = 7/5
3x + 2y = 10
3x + 2(7/5) = 10
3x + 14/5 = 10
3x = 10 - 14/5
3x = 50/5 - 14/5
3x = 36/5
x = 36/5 : 3
x = 36/15
HP = {7/5, 36/15}
