3x=2-4y
Tangohia te 4y mai i ngā taha e rua.
\frac{3x}{3}=\frac{2-4y}{3}
Whakawehea ngā taha e rua ki te 3.
x=\frac{2-4y}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
4y=2-3x
Tangohia te 3x mai i ngā taha e rua.
\frac{4y}{4}=\frac{2-3x}{4}
Whakawehea ngā taha e rua ki te 4.
y=\frac{2-3x}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
y=-\frac{3x}{4}+\frac{1}{2}
Whakawehe 2-3x ki te 4.
