Whakaoti mō x
\left\{\begin{matrix}x=\frac{5y}{4-z}\text{, }&z\neq 4\\x\in \mathrm{R}\text{, }&y=0\text{ and }z=4\end{matrix}\right.
Whakaoti mō y
y=-\frac{x\left(z-4\right)}{5}

Kua tāruatia ki te papatopenga
4x-zx=5y
Tangohia te zx mai i ngā taha e rua.
\left(4-z\right)x=5y
Pahekotia ngā kīanga tau katoa e whai ana i te x.
\frac{\left(4-z\right)x}{4-z}=\frac{5y}{4-z}
Whakawehea ngā taha e rua ki te -z+4.
x=\frac{5y}{4-z}
Mā te whakawehe ki te -z+4 ka wetekia te whakareanga ki te -z+4.
5y+zx=4x
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
5y=4x-zx
Tangohia te zx mai i ngā taha e rua.
5y=4x-xz
He hanga arowhānui tō te whārite.
\frac{5y}{5}=\frac{x\left(4-z\right)}{5}
Whakawehea ngā taha e rua ki te 5.
y=\frac{x\left(4-z\right)}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
y=\frac{4x-xz}{5}
Whakawehe x\left(4-z\right) ki te 5.
