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