Tohaina
Kua tāruatia ki te papatopenga
y=2x+3z-9
Me whakaoti te 2x-y+3z=9 mō y.
x+2x+3z-9+z=6 x-\left(2x+3z-9\right)+z=2
Whakakapia te 2x+3z-9 mō te y i te whārite tuarua me te tuatoru.
x=-\frac{4}{3}z+5 z=-\frac{1}{2}x+\frac{7}{2}
Me whakaoti ēnei whārite mō x me z takitahi.
z=-\frac{1}{2}\left(-\frac{4}{3}z+5\right)+\frac{7}{2}
Whakakapia te -\frac{4}{3}z+5 mō te x i te whārite z=-\frac{1}{2}x+\frac{7}{2}.
z=3
Me whakaoti te z=-\frac{1}{2}\left(-\frac{4}{3}z+5\right)+\frac{7}{2} mō z.
x=-\frac{4}{3}\times 3+5
Whakakapia te 3 mō te z i te whārite x=-\frac{4}{3}z+5.
x=1
Tātaitia te x i te x=-\frac{4}{3}\times 3+5.
y=2\times 1+3\times 3-9
Whakakapia te 1 mō te x me te 3 mō z i te whārite y=2x+3z-9.
y=2
Tātaitia te y i te y=2\times 1+3\times 3-9.
x=1 y=2 z=3
Kua oti te pūnaha te whakatau.
