y=-3
z=4
Tohaina
Kua tāruatia ki te papatopenga
x=6y+3z+4
Me whakaoti te x-6y-3z=4 mō x.
-2\left(6y+3z+4\right)-3z=-8 -2\left(6y+3z+4\right)+2y-3z=-14
Whakakapia te 6y+3z+4 mō te x i te whārite tuarua me te tuatoru.
y=-\frac{3}{4}z z=\frac{2}{3}-\frac{10}{9}y
Me whakaoti ēnei whārite mō y me z takitahi.
z=\frac{2}{3}-\frac{10}{9}\left(-\frac{3}{4}\right)z
Whakakapia te -\frac{3}{4}z mō te y i te whārite z=\frac{2}{3}-\frac{10}{9}y.
z=4
Me whakaoti te z=\frac{2}{3}-\frac{10}{9}\left(-\frac{3}{4}\right)z mō z.
y=-\frac{3}{4}\times 4
Whakakapia te 4 mō te z i te whārite y=-\frac{3}{4}z.
y=-3
Tātaitia te y i te y=-\frac{3}{4}\times 4.
x=6\left(-3\right)+3\times 4+4
Whakakapia te -3 mō te y me te 4 mō z i te whārite x=6y+3z+4.
x=-2
Tātaitia te x i te x=6\left(-3\right)+3\times 4+4.
x=-2 y=-3 z=4
Kua oti te pūnaha te whakatau.
