Whakaoti mō a (complex solution)
\left\{\begin{matrix}a=\frac{7x+b-8}{x}\text{, }&x\neq 0\\a\in \mathrm{C}\text{, }&x=0\text{ and }b=8\end{matrix}\right.
Whakaoti mō a
\left\{\begin{matrix}a=\frac{7x+b-8}{x}\text{, }&x\neq 0\\a\in \mathrm{R}\text{, }&x=0\text{ and }b=8\end{matrix}\right.
Whakaoti mō b
b=ax-7x+8

Kua tāruatia ki te papatopenga
ax=7x+b-8
Tangohia te 8 mai i ngā taha e rua.
xa=7x+b-8
He hanga arowhānui tō te whārite.
\frac{xa}{x}=\frac{7x+b-8}{x}
Whakawehea ngā taha e rua ki te x.
a=\frac{7x+b-8}{x}
Mā te whakawehe ki te x ka wetekia te whakareanga ki te x.
ax=7x+b-8
Tangohia te 8 mai i ngā taha e rua.
xa=7x+b-8
He hanga arowhānui tō te whārite.
\frac{xa}{x}=\frac{7x+b-8}{x}
Whakawehea ngā taha e rua ki te x.
a=\frac{7x+b-8}{x}
Mā te whakawehe ki te x ka wetekia te whakareanga ki te x.
7x+b=ax+8
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
b=ax+8-7x
Tangohia te 7x mai i ngā taha e rua.
