Tentukan nilai x dan y pada persamaan matriks berikut diatas (x+y 3)=(5 3) Dibawah (2 x-y) = (2 1)

X=3
y=2

X+y = 5
x-y = 1

x+y=5
x-y=1
_______-
2y = 4
y= 2

substitusi y= 2
x+y=5
x+2=5
x=5-2
x=3

| x+y 3 | | 5 3 |
=
| 2 x-y | | 2 1 |

x + y = 5
x - y = 1
_______+
2x= 6
x= 6/2
x= 3

x - y = 1
3 - y = 1
-y = 1-3
-y = -2
y = 2
