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