x+2y-21xy=0
Tangohia te 21xy mai i ngā taha e rua.
x-21xy=-2y
Tangohia te 2y mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
\left(1-21y\right)x=-2y
Pahekotia ngā kīanga tau katoa e whai ana i te x.
\frac{\left(1-21y\right)x}{1-21y}=-\frac{2y}{1-21y}
Whakawehea ngā taha e rua ki te 1-21y.
x=-\frac{2y}{1-21y}
Mā te whakawehe ki te 1-21y ka wetekia te whakareanga ki te 1-21y.
x+2y-21xy=0
Tangohia te 21xy mai i ngā taha e rua.
2y-21xy=-x
Tangohia te x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
\left(2-21x\right)y=-x
Pahekotia ngā kīanga tau katoa e whai ana i te y.
\frac{\left(2-21x\right)y}{2-21x}=-\frac{x}{2-21x}
Whakawehea ngā taha e rua ki te 2-21x.
y=-\frac{x}{2-21x}
Mā te whakawehe ki te 2-21x ka wetekia te whakareanga ki te 2-21x.
