9x+8y-xy=0
Tangohia te xy mai i ngā taha e rua.
9x-xy=-8y
Tangohia te 8y mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
\left(9-y\right)x=-8y
Pahekotia ngā kīanga tau katoa e whai ana i te x.
\frac{\left(9-y\right)x}{9-y}=-\frac{8y}{9-y}
Whakawehea ngā taha e rua ki te 9-y.
x=-\frac{8y}{9-y}
Mā te whakawehe ki te 9-y ka wetekia te whakareanga ki te 9-y.
9x+8y-xy=0
Tangohia te xy mai i ngā taha e rua.
8y-xy=-9x
Tangohia te 9x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
\left(8-x\right)y=-9x
Pahekotia ngā kīanga tau katoa e whai ana i te y.
\frac{\left(8-x\right)y}{8-x}=-\frac{9x}{8-x}
Whakawehea ngā taha e rua ki te 8-x.
y=-\frac{9x}{8-x}
Mā te whakawehe ki te 8-x ka wetekia te whakareanga ki te 8-x.
