Whakaoti mō c
\left\{\begin{matrix}c=\frac{a}{7m}\text{, }&m\neq 0\\c\in \mathrm{R}\text{, }&a=0\text{ and }m=0\end{matrix}\right.
Whakaoti mō a
a=7cm
Tohaina
Kua tāruatia ki te papatopenga
7cm=a
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
7mc=a
He hanga arowhānui tō te whārite.
\frac{7mc}{7m}=\frac{a}{7m}
Whakawehea ngā taha e rua ki te 7m.
c=\frac{a}{7m}
Mā te whakawehe ki te 7m ka wetekia te whakareanga ki te 7m.
