Whakaoti mō x, y, z
x=a+3
y=-a
z=a
Tohaina
Kua tāruatia ki te papatopenga
x=z+3 z=a
Me whakaoti te whārite tuarua mō x me te whārite tuatoru mō z.
x=a+3
Whakakapia te a mō te z i te whārite x=z+3.
y=3-\left(3+a\right)
Whakakapia te 3+a mō te x i te whārite y=3-x.
y=-a
Tātaitia te y i te y=3-\left(3+a\right).
x=a+3 y=-a z=a
Kua oti te pūnaha te whakatau.
Ngā Tauira
whārite tapawhā
