tentukan nilai x dan y 2x - 3y = 16 -5x + y = -27

2x-3y=16 (×1)
-5x+y=-27(×-3)

>> 2x-3y=16
15x-3y= 81
_________________-
-13x= - 65
x= 5

2x-3y=16
2(5)-3y=16
10-3y=16
-3y=16-10
-3y= 6
y = -2

2x - 3y = 16 | x5 |
-5x + y = -27 |x2 |

10x - 15y = 80
-10x + 2y = -54 +
-13y = 26
y = [tex] \frac{26}{-13} [/tex]
y = -2
