2x+3=-4y
Tangohia te 4y mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
2x=-4y-3
Tangohia te 3 mai i ngā taha e rua.
\frac{2x}{2}=\frac{-4y-3}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{-4y-3}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=-2y-\frac{3}{2}
Whakawehe -4y-3 ki te 2.
4y+3=-2x
Tangohia te 2x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
4y=-2x-3
Tangohia te 3 mai i ngā taha e rua.
\frac{4y}{4}=\frac{-2x-3}{4}
Whakawehea ngā taha e rua ki te 4.
y=\frac{-2x-3}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
y=-\frac{x}{2}-\frac{3}{4}
Whakawehe -2x-3 ki te 4.
