Kua tāruatia ki te papatopenga
x=-y+5
Me whakaoti te x+y=5 mō x.
z-y+5=7
Whakakapia te -y+5 mō te x i te whārite z+x=7.
y=-z+6 z=y+2
Me whakaoti te whārite tuarua mō y me te whārite tuatoru mō z.
z=-z+6+2
Whakakapia te -z+6 mō te y i te whārite z=y+2.
z=4
Me whakaoti te z=-z+6+2 mō z.
y=-4+6
Whakakapia te 4 mō te z i te whārite y=-z+6.
y=2
Tātaitia te y i te y=-4+6.
x=-2+5
Whakakapia te 2 mō te y i te whārite x=-y+5.
x=3
Tātaitia te x i te x=-2+5.
