Tohaina
Kua tāruatia ki te papatopenga
2y-z+y+z=6 2y-z-y+2z=5
Whakakapia te 2y-z mō te x i te whārite tuarua me te tuatoru.
y=2 z=-y+5
Me whakaoti ēnei whārite mō y me z takitahi.
z=-2+5
Whakakapia te 2 mō te y i te whārite z=-y+5.
z=3
Tātaitia te z i te z=-2+5.
x=2\times 2-3
Whakakapia te 2 mō te y me te 3 mō z i te whārite x=2y-z.
x=1
Tātaitia te x i te x=2\times 2-3.
x=1 y=2 z=3
Kua oti te pūnaha te whakatau.
