z=0
Tohaina
Kua tāruatia ki te papatopenga
y=9-3x
Me whakaoti te 3x+y=9 mō y.
9-3x+z=3 x-\left(9-3x\right)=-1
Whakakapia te 9-3x mō te y i te whārite tuarua me te tuatoru.
z=-6+3x x=2
Me whakaoti ēnei whārite mō z me x takitahi.
z=-6+3\times 2
Whakakapia te 2 mō te x i te whārite z=-6+3x.
z=0
Tātaitia te z i te z=-6+3\times 2.
y=9-3\times 2
Whakakapia te 2 mō te x i te whārite y=9-3x.
y=3
Tātaitia te y i te y=9-3\times 2.
x=2 y=3 z=0
Kua oti te pūnaha te whakatau.
