2x+5y-2xy=0
Tangohia te 2xy mai i ngā taha e rua.
2x-2xy=-5y
Tangohia te 5y mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
\left(2-2y\right)x=-5y
Pahekotia ngā kīanga tau katoa e whai ana i te x.
\frac{\left(2-2y\right)x}{2-2y}=-\frac{5y}{2-2y}
Whakawehea ngā taha e rua ki te -2y+2.
x=-\frac{5y}{2-2y}
Mā te whakawehe ki te -2y+2 ka wetekia te whakareanga ki te -2y+2.
x=-\frac{5y}{2\left(1-y\right)}
Whakawehe -5y ki te -2y+2.
2x+5y-2xy=0
Tangohia te 2xy mai i ngā taha e rua.
5y-2xy=-2x
Tangohia te 2x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
\left(5-2x\right)y=-2x
Pahekotia ngā kīanga tau katoa e whai ana i te y.
\frac{\left(5-2x\right)y}{5-2x}=-\frac{2x}{5-2x}
Whakawehea ngā taha e rua ki te 5-2x.
y=-\frac{2x}{5-2x}
Mā te whakawehe ki te 5-2x ka wetekia te whakareanga ki te 5-2x.
