2x-y=6 3x+y=4 Cari hp nya,beserta jalannya nya!

2x - y = 6
2x - 6 = y

3x + y = 4
3x + 2x - 6 = 4
5x - 6 = 4
5x = 10
x = 2

jika x = 2 maka 
y = 2x - 6 = 2.2 - 6 = 4 - 6 = -2

HP = {(2, -2)}

2x-y = 6
2x - y - 6 = 0
2x - 6 = y
y = 2x - 6

3x + y = 4
y = -3x +4

2x - 6 = -3x +4
2x + 3x = 4 + 6
5x = 10
x = 2

eliminasi x =2 ke persamaan y = 2x -6
y = 2x - 6
y = 2(2) -6
y = 4 - 6
y = -2

hp = {2,-2)
