Whakaoti mō x, y, z
x=\frac{a-6}{4}
y=-2
z=a
Tohaina
Kua tāruatia ki te papatopenga
x=\frac{1}{4}z-\frac{3}{2} z=a
Me whakaoti te whārite tuarua mō x me te whārite tuatoru mō z.
x=\frac{1}{4}a-\frac{3}{2}
Whakakapia te a mō te z i te whārite x=\frac{1}{4}z-\frac{3}{2}.
x=\frac{1}{4}a-\frac{3}{2} y=-2 z=a
Kua oti te pūnaha te whakatau.
