Tentunkan Penyelesaian sistem persamaan linear dua variabel {x-y=6 {2x+3y=7

x - y = 6      |kali 2|
2x + 3y = 7 |kali 1|
______________ -
- 5y = 5
y = -1
x = 5

x-y=6     (X2) --> 2x-2y=12
2x+3y=7 (x1) -->2x+3y=7  _
                         -5y = 5 --> y=-1
x-y=6  
x-(-1) = 6
x = 6-1
y = 5

Hp = {(5,-1)}
