-3x+8y-z=2 4x+2y-3z=-10 3x+2y-2z=-8
Me raupapa anō ngā whārite.
z=-3x+8y-2
Me whakaoti te -3x+8y-z=2 mō z.
4x+2y-3\left(-3x+8y-2\right)=-10 3x+2y-2\left(-3x+8y-2\right)=-8
Whakakapia te -3x+8y-2 mō te z i te whārite tuarua me te tuatoru.
y=\frac{13}{22}x+\frac{8}{11} x=-\frac{4}{3}+\frac{14}{9}y
Me whakaoti ēnei whārite mō y me x takitahi.
x=-\frac{4}{3}+\frac{14}{9}\left(\frac{13}{22}x+\frac{8}{11}\right)
Whakakapia te \frac{13}{22}x+\frac{8}{11} mō te y i te whārite x=-\frac{4}{3}+\frac{14}{9}y.
x=-\frac{5}{2}
Me whakaoti te x=-\frac{4}{3}+\frac{14}{9}\left(\frac{13}{22}x+\frac{8}{11}\right) mō x.
y=\frac{13}{22}\left(-\frac{5}{2}\right)+\frac{8}{11}
Whakakapia te -\frac{5}{2} mō te x i te whārite y=\frac{13}{22}x+\frac{8}{11}.
y=-\frac{3}{4}
Tātaitia te y i te y=\frac{13}{22}\left(-\frac{5}{2}\right)+\frac{8}{11}.
z=-3\left(-\frac{5}{2}\right)+8\left(-\frac{3}{4}\right)-2
Whakakapia te -\frac{3}{4} mō te y me te -\frac{5}{2} mō x i te whārite z=-3x+8y-2.
z=-\frac{1}{2}
Tātaitia te z i te z=-3\left(-\frac{5}{2}\right)+8\left(-\frac{3}{4}\right)-2.
x=-\frac{5}{2} y=-\frac{3}{4} z=-\frac{1}{2}
Kua oti te pūnaha te whakatau.
