Whakaoti mō x
\left\{\begin{matrix}\\x=2z\text{, }&\text{unconditionally}\\x\in \mathrm{R}\text{, }&y=0\end{matrix}\right.
Whakaoti mō y
\left\{\begin{matrix}\\y=0\text{, }&\text{unconditionally}\\y\in \mathrm{R}\text{, }&x=2z\end{matrix}\right.
Tohaina
Kua tāruatia ki te papatopenga
xy=2yz
Whakaraupapatia anō ngā kīanga tau.
yx=2yz
He hanga arowhānui tō te whārite.
\frac{yx}{y}=\frac{2yz}{y}
Whakawehea ngā taha e rua ki te y.
x=\frac{2yz}{y}
Mā te whakawehe ki te y ka wetekia te whakareanga ki te y.
x=2z
Whakawehe 2yz ki te y.
1xy-2yz=0
Tangohia te 2yz mai i ngā taha e rua.
xy-2yz=0
Whakaraupapatia anō ngā kīanga tau.
\left(x-2z\right)y=0
Pahekotia ngā kīanga tau katoa e whai ana i te y.
y=0
Whakawehe 0 ki te x-2z.
