Whakaoti mō d
\left\{\begin{matrix}d=\frac{y}{x\times 7^{x}}\text{, }&x\neq 0\\d\in \mathrm{R}\text{, }&y=0\text{ and }x=0\end{matrix}\right.

Kua tāruatia ki te papatopenga
7^{x}dx=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x\times 7^{x}d=y
He hanga arowhānui tō te whārite.
\frac{x\times 7^{x}d}{x\times 7^{x}}=\frac{y}{x\times 7^{x}}
Whakawehea ngā taha e rua ki te 7^{x}x.
d=\frac{y}{x\times 7^{x}}
Mā te whakawehe ki te 7^{x}x ka wetekia te whakareanga ki te 7^{x}x.
