z-y+8=4
Whakakapia te -y+8 mō te x i te whārite z+x=4.
y=-z+6 z=y-4
Me whakaoti te whārite tuarua mō y me te whārite tuatoru mō z.
z=-z+6-4
Whakakapia te -z+6 mō te y i te whārite z=y-4.
z=1
Me whakaoti te z=-z+6-4 mō z.
y=-1+6
Whakakapia te 1 mō te z i te whārite y=-z+6.
y=5
Tātaitia te y i te y=-1+6.
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.
