Tohaina
Kua tāruatia ki te papatopenga
y=-z+2
Me whakaoti te y+z=2 mō y.
x-z+2=5
Whakakapia te -z+2 mō te y i te whārite x+y=5.
z=-x+5 x=z+3
Me whakaoti te whārite tuarua mō z me te whārite tuatoru mō x.
x=-x+5+3
Whakakapia te -x+5 mō te z i te whārite x=z+3.
x=4
Me whakaoti te x=-x+5+3 mō x.
z=-4+5
Whakakapia te 4 mō te x i te whārite z=-x+5.
z=1
Tātaitia te z i te z=-4+5.
y=-1+2
Whakakapia te 1 mō te z i te whārite y=-z+2.
y=1
Tātaitia te y i te y=-1+2.
y=1 z=1 x=4
Kua oti te pūnaha te whakatau.
