y=-4-2x
Me whakaoti te 2x+y=-4 mō y.
-2\left(-4-2x\right)+4z=0
Whakakapia te -4-2x mō te y i te whārite -2y+4z=0.
x=-2-z z=\frac{3}{2}x+\frac{11}{2}
Me whakaoti te whārite tuarua mō x me te whārite tuatoru mō z.
z=\frac{3}{2}\left(-2-z\right)+\frac{11}{2}
Whakakapia te -2-z mō te x i te whārite z=\frac{3}{2}x+\frac{11}{2}.
z=1
Me whakaoti te z=\frac{3}{2}\left(-2-z\right)+\frac{11}{2} mō z.
x=-2-1
Whakakapia te 1 mō te z i te whārite x=-2-z.
x=-3
Tātaitia te x i te x=-2-1.
y=-4-2\left(-3\right)
Whakakapia te -3 mō te x i te whārite y=-4-2x.
y=2
Tātaitia te y i te y=-4-2\left(-3\right).
