Kua tāruatia ki te papatopenga
xy-2x=1
Tangohia te 2x mai i ngā taha e rua.
\left(y-2\right)x=1
Pahekotia ngā kīanga tau katoa e whai ana i te x.
\frac{\left(y-2\right)x}{y-2}=\frac{1}{y-2}
Whakawehea ngā taha e rua ki te y-2.
x=\frac{1}{y-2}
Mā te whakawehe ki te y-2 ka wetekia te whakareanga ki te y-2.
xy=2x+1
He hanga arowhānui tō te whārite.
\frac{xy}{x}=\frac{2x+1}{x}
Whakawehea ngā taha e rua ki te x.
y=\frac{2x+1}{x}
Mā te whakawehe ki te x ka wetekia te whakareanga ki te x.
y=2+\frac{1}{x}
Whakawehe 2x+1 ki te x.
