2x=18-4y
Tangohia te 4y mai i ngā taha e rua.
\frac{2x}{2}=\frac{18-4y}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{18-4y}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=9-2y
Whakawehe 18-4y ki te 2.
4y=18-2x
Tangohia te 2x mai i ngā taha e rua.
\frac{4y}{4}=\frac{18-2x}{4}
Whakawehea ngā taha e rua ki te 4.
y=\frac{18-2x}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
y=\frac{9-x}{2}
Whakawehe 18-2x ki te 4.
