z=6
Tohaina
Kua tāruatia ki te papatopenga
x=3y-3z-2
Me whakaoti te -x+3y-3z=2 mō x.
2\left(3y-3z-2\right)-y+2z=7
Whakakapia te 3y-3z-2 mō te x i te whārite 2x-y+2z=7.
y=z+1 z=\frac{5}{4}y-\frac{11}{4}
Me whakaoti te whārite tuarua mō y me te whārite tuatoru mō z.
z=\frac{5}{4}\left(z+1\right)-\frac{11}{4}
Whakakapia te z+1 mō te y i te whārite z=\frac{5}{4}y-\frac{11}{4}.
z=6
Me whakaoti te z=\frac{5}{4}\left(z+1\right)-\frac{11}{4} mō z.
y=6+1
Whakakapia te 6 mō te z i te whārite y=z+1.
y=7
Tātaitia te y i te y=6+1.
x=3\times 7-3\times 6-2
Whakakapia te 7 mō te y me te 6 mō z i te whārite x=3y-3z-2.
x=1
Tātaitia te x i te x=3\times 7-3\times 6-2.
x=1 y=7 z=6
Kua oti te pūnaha te whakatau.
