Himpunan penyelesaian dari sistem persamaan 5 x tambah 2 y = -2 dan 2x dikurang 3y = -16 adalah

5x + 2y = -2
2x – 3y = -16

↓ metode eliminasi (samakan x)

10x + 4y = -4
10x -15y = -80
___________- (kurangi)
19y = 76
y = 4

↓ (metode substitusi)

5x + 2.4 = -2
5x + 8 = -2
5x = -10
x = -2

HP = {-2, 4}

5x + 2y = -2 | 2 | 10x + 4y = -4
2x – 3y = -16 | 5 | 10x – 15y = -80
………………………… –
19y = 76
y = 4

2x – 3y = -16
2x – 3(4) = -16
2x – 12 = -16
2x = -16 + 12
2x = -4
x = -2
