5x+20=-2y
Tangohia te 2y mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
5x=-2y-20
Tangohia te 20 mai i ngā taha e rua.
\frac{5x}{5}=\frac{-2y-20}{5}
Whakawehea ngā taha e rua ki te 5.
x=\frac{-2y-20}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
x=-\frac{2y}{5}-4
Whakawehe -2y-20 ki te 5.
2y+20=-5x
Tangohia te 5x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
2y=-5x-20
Tangohia te 20 mai i ngā taha e rua.
\frac{2y}{2}=\frac{-5x-20}{2}
Whakawehea ngā taha e rua ki te 2.
y=\frac{-5x-20}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
y=-\frac{5x}{2}-10
Whakawehe -5x-20 ki te 2.
