Tohaina
Kua tāruatia ki te papatopenga
x=-2y+3
Me whakaoti te x+2y=3 mō x.
-2y+3+y+z=5 -2y+3+3y=7
Whakakapia te -2y+3 mō te x i te whārite tuarua me te tuatoru.
z=y+2 y=4
Me whakaoti ēnei whārite mō z me y takitahi.
z=4+2
Whakakapia te 4 mō te y i te whārite z=y+2.
z=6
Tātaitia te z i te z=4+2.
x=-2\times 4+3
Whakakapia te 4 mō te y i te whārite x=-2y+3.
x=-5
Tātaitia te x i te x=-2\times 4+3.
x=-5 y=4 z=6
Kua oti te pūnaha te whakatau.
