\left(y+1\right)x=9
Pahekotia ngā kīanga tau katoa e whai ana i te x.
\frac{\left(y+1\right)x}{y+1}=\frac{9}{y+1}
Whakawehea ngā taha e rua ki te y+1.
x=\frac{9}{y+1}
Mā te whakawehe ki te y+1 ka wetekia te whakareanga ki te y+1.
xy=9-x
Tangohia te x mai i ngā taha e rua.
\frac{xy}{x}=\frac{9-x}{x}
Whakawehea ngā taha e rua ki te x.
y=\frac{9-x}{x}
Mā te whakawehe ki te x ka wetekia te whakareanga ki te x.
y=-1+\frac{9}{x}
Whakawehe 9-x ki te x.
