2x+1=-8y
Tangohia te 8y mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
2x=-8y-1
Tangohia te 1 mai i ngā taha e rua.
\frac{2x}{2}=\frac{-8y-1}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{-8y-1}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=-4y-\frac{1}{2}
Whakawehe -8y-1 ki te 2.
8y+1=-2x
Tangohia te 2x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
8y=-2x-1
Tangohia te 1 mai i ngā taha e rua.
\frac{8y}{8}=\frac{-2x-1}{8}
Whakawehea ngā taha e rua ki te 8.
y=\frac{-2x-1}{8}
Mā te whakawehe ki te 8 ka wetekia te whakareanga ki te 8.
y=-\frac{x}{4}-\frac{1}{8}
Whakawehe -2x-1 ki te 8.
