Whakaoti mō x
\left\{\begin{matrix}x=-\frac{z-y}{z-2}\text{, }&z\neq 2\\x\in \mathrm{R}\text{, }&z=2\text{ and }y=2\end{matrix}\right.
Whakaoti mō y
y=xz-2x+z
Tohaina
Kua tāruatia ki te papatopenga
\left(z-2\right)x=y-z
Pahekotia ngā kīanga tau katoa e whai ana i te x.
\frac{\left(z-2\right)x}{z-2}=\frac{y-z}{z-2}
Whakawehea ngā taha e rua ki te z-2.
x=\frac{y-z}{z-2}
Mā te whakawehe ki te z-2 ka wetekia te whakareanga ki te z-2.
y-z=zx-2x
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
y=zx-2x+z
Me tāpiri te z ki ngā taha e rua.
