Kua tāruatia ki te papatopenga
\left(1+2y\right)x=7
Pahekotia ngā kīanga tau katoa e whai ana i te x.
\left(2y+1\right)x=7
He hanga arowhānui tō te whārite.
\frac{\left(2y+1\right)x}{2y+1}=\frac{7}{2y+1}
Whakawehea ngā taha e rua ki te 1+2y.
x=\frac{7}{2y+1}
Mā te whakawehe ki te 1+2y ka wetekia te whakareanga ki te 1+2y.
2xy=7-x
Tangohia te x mai i ngā taha e rua.
\frac{2xy}{2x}=\frac{7-x}{2x}
Whakawehea ngā taha e rua ki te 2x.
y=\frac{7-x}{2x}
Mā te whakawehe ki te 2x ka wetekia te whakareanga ki te 2x.
y=-\frac{1}{2}+\frac{7}{2x}
Whakawehe 7-x ki te 2x.
