Tohaina
Kua tāruatia ki te papatopenga
ab-a-a=-b
Tangohia te 1a mai i ngā taha e rua.
ab-2a=-b
Pahekotia te -a me -a, ka -2a.
\left(b-2\right)a=-b
Pahekotia ngā kīanga tau katoa e whai ana i te a.
\frac{\left(b-2\right)a}{b-2}=-\frac{b}{b-2}
Whakawehea ngā taha e rua ki te b-2.
a=-\frac{b}{b-2}
Mā te whakawehe ki te b-2 ka wetekia te whakareanga ki te b-2.
ab-a+b=1a
Me tāpiri te b ki ngā taha e rua.
ab+b=1a+a
Me tāpiri te a ki ngā taha e rua.
ab+b=2a
Pahekotia te 1a me a, ka 2a.
\left(a+1\right)b=2a
Pahekotia ngā kīanga tau katoa e whai ana i te b.
\frac{\left(a+1\right)b}{a+1}=\frac{2a}{a+1}
Whakawehea ngā taha e rua ki te a+1.
b=\frac{2a}{a+1}
Mā te whakawehe ki te a+1 ka wetekia te whakareanga ki te a+1.
