Whakaoti mō a (complex solution)
\left\{\begin{matrix}a=-\frac{9-7x}{y}\text{, }&y\neq 0\\a\in \mathrm{C}\text{, }&x=\frac{9}{7}\text{ and }y=0\end{matrix}\right.
Whakaoti mō a
\left\{\begin{matrix}a=-\frac{9-7x}{y}\text{, }&y\neq 0\\a\in \mathrm{R}\text{, }&x=\frac{9}{7}\text{ and }y=0\end{matrix}\right.
Whakaoti mō x

ya=7x-9
He hanga arowhānui tō te whārite.
\frac{ya}{y}=\frac{7x-9}{y}
Whakawehea ngā taha e rua ki te y.
a=\frac{7x-9}{y}
Mā te whakawehe ki te y ka wetekia te whakareanga ki te y.
ya=7x-9
He hanga arowhānui tō te whārite.
\frac{ya}{y}=\frac{7x-9}{y}
Whakawehea ngā taha e rua ki te y.
a=\frac{7x-9}{y}
Mā te whakawehe ki te y ka wetekia te whakareanga ki te y.
7x-9=ay
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
7x=ay+9
Me tāpiri te 9 ki ngā taha e rua.
\frac{7x}{7}=\frac{ay+9}{7}
Whakawehea ngā taha e rua ki te 7.
x=\frac{ay+9}{7}
Mā te whakawehe ki te 7 ka wetekia te whakareanga ki te 7.
