\left\{ \begin{array} { l } { x + 1 - 2 y = 0 } \\ { y + z - 2 = 0 } \\ { 2 x + y - z - 6 = 0 } \end{array} \right.
Whakaoti mō x, y, z
x = \frac{7}{3} = 2\frac{1}{3} \approx 2.333333333
y = \frac{5}{3} = 1\frac{2}{3} \approx 1.666666667
z=\frac{1}{3}\approx 0.333333333
Tohaina
Kua tāruatia ki te papatopenga
x=-1+2y
Me whakaoti te x+1-2y=0 mō x.
2\left(-1+2y\right)+y-z-6=0
Whakakapia te -1+2y mō te x i te whārite 2x+y-z-6=0.
y=-z+2 z=-8+5y
Me whakaoti te whārite tuarua mō y me te whārite tuatoru mō z.
z=-8+5\left(-z+2\right)
Whakakapia te -z+2 mō te y i te whārite z=-8+5y.
z=\frac{1}{3}
Me whakaoti te z=-8+5\left(-z+2\right) mō z.
y=-\frac{1}{3}+2
Whakakapia te \frac{1}{3} mō te z i te whārite y=-z+2.
y=\frac{5}{3}
Tātaitia te y i te y=-\frac{1}{3}+2.
x=-1+2\times \frac{5}{3}
Whakakapia te \frac{5}{3} mō te y i te whārite x=-1+2y.
x=\frac{7}{3}
Tātaitia te x i te x=-1+2\times \frac{5}{3}.
x=\frac{7}{3} y=\frac{5}{3} z=\frac{1}{3}
Kua oti te pūnaha te whakatau.
