Kua tāruatia ki te papatopenga
x=-y+8
Me whakaoti te x+y=8 mō x.
3\left(-y+8\right)-y-a=0 -y+8-2y+a+3=0
Whakakapia te -y+8 mō te x i te whārite tuarua me te tuatoru.
y=6-\frac{1}{4}a a=3y-11
Me whakaoti ēnei whārite mō y me a takitahi.
a=3\left(6-\frac{1}{4}a\right)-11
Whakakapia te 6-\frac{1}{4}a mō te y i te whārite a=3y-11.
a=4
Me whakaoti te a=3\left(6-\frac{1}{4}a\right)-11 mō a.
y=6-\frac{1}{4}\times 4
Whakakapia te 4 mō te a i te whārite y=6-\frac{1}{4}a.
y=5
Tātaitia te y i te y=6-\frac{1}{4}\times 4.
x=-5+8
Whakakapia te 5 mō te y i te whārite x=-y+8.
x=3
Tātaitia te x i te x=-5+8.
