Tohaina
Kua tāruatia ki te papatopenga
x=-y+z+11
Me whakaoti te x+y-z=11 mō x.
-\left(-y+z+11\right)+y+z=5 -y+z+11-y+z=1
Whakakapia te -y+z+11 mō te x i te whārite tuarua me te tuatoru.
y=8 z=-5+y
Me whakaoti ēnei whārite mō y me z takitahi.
z=-5+8
Whakakapia te 8 mō te y i te whārite z=-5+y.
z=3
Tātaitia te z i te z=-5+8.
x=-8+3+11
Whakakapia te 8 mō te y me te 3 mō z i te whārite x=-y+z+11.
x=6
Tātaitia te x i te x=-8+3+11.
x=6 y=8 z=3
Kua oti te pūnaha te whakatau.
