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