Tohaina
Kua tāruatia ki te papatopenga
x=-y+4
Me whakaoti te x+y=4 mō x.
-y+4+z=-2
Whakakapia te -y+4 mō te x i te whārite x+z=-2.
y=-z+6 z=-6+y
Me whakaoti te whārite tuarua mō y me te whārite tuatoru mō z.
z=-6-z+6
Whakakapia te -z+6 mō te y i te whārite z=-6+y.
z=0
Me whakaoti te z=-6-z+6 mō z.
y=-0+6
Whakakapia te 0 mō te z i te whārite y=-z+6.
y=6
Tātaitia te y i te y=-0+6.
x=-6+4
Whakakapia te 6 mō te y i te whārite x=-y+4.
x=-2
Tātaitia te x i te x=-6+4.
x=-2 y=6 z=0
