masukkan ke dalam persamaan yang lain :
2x=y-10
di ubah menjadi :
2x-y+10=0
2(2y+8)-y+10=0
4y+16-y+10=0
4y-y=-16-10
3y=-26
y=-9
dimasukkan :
x=2y+8
x=2(-9)+8
x=-18+8
x=-10

ambil➡2x=y-10
2x-y=-10
-y=-10-2x
y=10+2x
ambil➡x=2y+8
x-2y=8
x-2(10+2x)=8
x-20-4x=8
-3x=8+20
-3x=28
x per-3=28per-3
x=-9,33
subsitusi➡2x=y-10
2(-9,33)=y-10
-18,66=y-10
-y=-10+18,66
-y=8,66
y=-8,66
penyelesaian (-9,33,-8,66)
