4x=-9y
Tangohia te 9y mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
\frac{4x}{4}=-\frac{9y}{4}
Whakawehea ngā taha e rua ki te 4.
x=-\frac{9y}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
9y=-4x
Tangohia te 4x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
\frac{9y}{9}=-\frac{4x}{9}
Whakawehea ngā taha e rua ki te 9.
y=-\frac{4x}{9}
Mā te whakawehe ki te 9 ka wetekia te whakareanga ki te 9.
