Sistem Persamaan linear dua vaiabel: 3x + 2y = 95 2x + y = 60 t Tentukan nilai x +2y!

3x + 2y = 95 |×2| 6x + 4y = 190
2x + y = 60 |×3| 6x + 3y = 180 (dikurangi)

6x+4y-6x-3y = 190-180
4y-3y = 10
y = 10

2x + y = 60
2x + (10) = 60
2x = 50
x = 25

x + 2y = 25 + 2(10) = 25 + 20 = 45

Semoga membantu yaa:)
