Selesaikan SPLDV dengn metode eliminasi dan metode substitusi: 2x-y=12 X+2y=14

2x-y=12 |1| → 2x-y= 12
x+2y=14|2|→ 2x+4y=28
……………………………… -
-5y = -16
y = -16/-5
y= 3 1/5
substitusikan
2x - (16/5) = 12
5(2x - 16/5) = 5(12)
10x -16 = 60
10 x = 60 +16
10x = 76
x = 76/10
x = 7 6/10
x = 7 3/5

maaf jika salah
