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