Whakaoti mō A
\left\{\begin{matrix}A=\frac{2a}{B}\text{, }&B\neq 0\\A\in \mathrm{R}\text{, }&a=0\text{ and }B=0\end{matrix}\right.
Whakaoti mō B
\left\{\begin{matrix}B=\frac{2a}{A}\text{, }&A\neq 0\\B\in \mathrm{R}\text{, }&a=0\text{ and }A=0\end{matrix}\right.
Tohaina
Kua tāruatia ki te papatopenga
BA=2a
He hanga arowhānui tō te whārite.
\frac{BA}{B}=\frac{2a}{B}
Whakawehea ngā taha e rua ki te B.
A=\frac{2a}{B}
Mā te whakawehe ki te B ka wetekia te whakareanga ki te B.
AB=2a
He hanga arowhānui tō te whārite.
\frac{AB}{A}=\frac{2a}{A}
Whakawehea ngā taha e rua ki te A.
B=\frac{2a}{A}
Mā te whakawehe ki te A ka wetekia te whakareanga ki te A.
