Kua tāruatia ki te papatopenga
xy-8y-x=9
Tangohia te x mai i ngā taha e rua.
xy-x=9+8y
Me tāpiri te 8y ki ngā taha e rua.
\left(y-1\right)x=9+8y
Pahekotia ngā kīanga tau katoa e whai ana i te x.
\left(y-1\right)x=8y+9
He hanga arowhānui tō te whārite.
\frac{\left(y-1\right)x}{y-1}=\frac{8y+9}{y-1}
Whakawehea ngā taha e rua ki te y-1.
x=\frac{8y+9}{y-1}
Mā te whakawehe ki te y-1 ka wetekia te whakareanga ki te y-1.
\left(x-8\right)y=x+9
Pahekotia ngā kīanga tau katoa e whai ana i te y.
\frac{\left(x-8\right)y}{x-8}=\frac{x+9}{x-8}
Whakawehea ngā taha e rua ki te x-8.
y=\frac{x+9}{x-8}
Mā te whakawehe ki te x-8 ka wetekia te whakareanga ki te x-8.
