x-xy+25=-y
Tangohia te y mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x-xy=-y-25
Tangohia te 25 mai i ngā taha e rua.
\left(1-y\right)x=-y-25
Pahekotia ngā kīanga tau katoa e whai ana i te x.
\frac{\left(1-y\right)x}{1-y}=\frac{-y-25}{1-y}
Whakawehea ngā taha e rua ki te 1-y.
x=\frac{-y-25}{1-y}
Mā te whakawehe ki te 1-y ka wetekia te whakareanga ki te 1-y.
x=-\frac{y+25}{1-y}
Whakawehe -y-25 ki te 1-y.
-xy+y+25=-x
Tangohia te x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
-xy+y=-x-25
Tangohia te 25 mai i ngā taha e rua.
\left(-x+1\right)y=-x-25
Pahekotia ngā kīanga tau katoa e whai ana i te y.
\left(1-x\right)y=-x-25
He hanga arowhānui tō te whārite.
\frac{\left(1-x\right)y}{1-x}=\frac{-x-25}{1-x}
Whakawehea ngā taha e rua ki te -x+1.
y=\frac{-x-25}{1-x}
Mā te whakawehe ki te -x+1 ka wetekia te whakareanga ki te -x+1.
y=-\frac{x+25}{1-x}
Whakawehe -x-25 ki te -x+1.
