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