10x+20=-50y
Tangohia te 50y mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
10x=-50y-20
Tangohia te 20 mai i ngā taha e rua.
\frac{10x}{10}=\frac{-50y-20}{10}
Whakawehea ngā taha e rua ki te 10.
x=\frac{-50y-20}{10}
Mā te whakawehe ki te 10 ka wetekia te whakareanga ki te 10.
x=-5y-2
Whakawehe -50y-20 ki te 10.
50y+20=-10x
Tangohia te 10x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
50y=-10x-20
Tangohia te 20 mai i ngā taha e rua.
\frac{50y}{50}=\frac{-10x-20}{50}
Whakawehea ngā taha e rua ki te 50.
y=\frac{-10x-20}{50}
Mā te whakawehe ki te 50 ka wetekia te whakareanga ki te 50.
y=\frac{-x-2}{5}
Whakawehe -10x-20 ki te 50.
