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