selesaikan lah dengan metode gabungan sumbtitusi dan eliminasi 2x + 10y = 14 5x - 9y = 1

2x + 10y = 14 |×5
5x - 9y = 1 |×2
maka
10x + 50y = 70
10x - 18y = 2
----------------------(-)
68y = 68
y = 1

subtitusi
2x + 10y = 14
2x + 10(1) = 14
2x = 14 - 10
2x = 4
x = 2

hp = ( 2 , 1 )

Semoga bermanfaat yah
