Whakaoti mō b (complex solution)
\left\{\begin{matrix}b=-\frac{cy-a}{x-1}\text{, }&x\neq 1\\b\in \mathrm{C}\text{, }&a=cy\text{ and }x=1\end{matrix}\right.
Whakaoti mō b
\left\{\begin{matrix}b=-\frac{cy-a}{x-1}\text{, }&x\neq 1\\b\in \mathrm{R}\text{, }&a=cy\text{ and }x=1\end{matrix}\right.
Whakaoti mō a
a=bx+cy-b

bx+cy-b=a
Tangohia te b mai i ngā taha e rua.
bx-b=a-cy
Tangohia te cy mai i ngā taha e rua.
\left(x-1\right)b=a-cy
Pahekotia ngā kīanga tau katoa e whai ana i te b.
\frac{\left(x-1\right)b}{x-1}=\frac{a-cy}{x-1}
Whakawehea ngā taha e rua ki te x-1.
b=\frac{a-cy}{x-1}
Mā te whakawehe ki te x-1 ka wetekia te whakareanga ki te x-1.
bx+cy-b=a
Tangohia te b mai i ngā taha e rua.
bx-b=a-cy
Tangohia te cy mai i ngā taha e rua.
\left(x-1\right)b=a-cy
Pahekotia ngā kīanga tau katoa e whai ana i te b.
\frac{\left(x-1\right)b}{x-1}=\frac{a-cy}{x-1}
Whakawehea ngā taha e rua ki te x-1.
b=\frac{a-cy}{x-1}
Mā te whakawehe ki te x-1 ka wetekia te whakareanga ki te x-1.
