Tohaina
Kua tāruatia ki te papatopenga
z=y 3x+8y=1 a=z
Me raupapa anō ngā whārite.
a=y
Whakakapia te y mō te z i te whārite a=z.
x=-\frac{8}{3}y+\frac{1}{3} y=a
Me whakaoti te whārite tuarua mō x me te whārite tuatoru mō y.
x=-\frac{8}{3}a+\frac{1}{3}
Whakakapia te a mō te y i te whārite x=-\frac{8}{3}y+\frac{1}{3}.
z=a
Whakakapia te a mō te y i te whārite z=y.
x=-\frac{8}{3}a+\frac{1}{3} y=a z=a
Kua oti te pūnaha te whakatau.
