Whakaoti mō x, y, z
x=7
y=9
z=3
Tohaina
Kua tāruatia ki te papatopenga
x=-y+16
Me whakaoti te x+y=16 mō x.
z-y+16=10
Whakakapia te -y+16 mō te x i te whārite z+x=10.
y=-z+12 z=y-6
Me whakaoti te whārite tuarua mō y me te whārite tuatoru mō z.
z=-z+12-6
Whakakapia te -z+12 mō te y i te whārite z=y-6.
z=3
Me whakaoti te z=-z+12-6 mō z.
y=-3+12
Whakakapia te 3 mō te z i te whārite y=-z+12.
y=9
Tātaitia te y i te y=-3+12.
x=-9+16
Whakakapia te 9 mō te y i te whārite x=-y+16.
x=7
Tātaitia te x i te x=-9+16.
x=7 y=9 z=3
Kua oti te pūnaha te whakatau.
