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