6x=18-6y
Tangohia te 6y mai i ngā taha e rua.
\frac{6x}{6}=\frac{18-6y}{6}
Whakawehea ngā taha e rua ki te 6.
x=\frac{18-6y}{6}
Mā te whakawehe ki te 6 ka wetekia te whakareanga ki te 6.
x=3-y
Whakawehe 18-6y ki te 6.
6y=18-6x
Tangohia te 6x mai i ngā taha e rua.
\frac{6y}{6}=\frac{18-6x}{6}
Whakawehea ngā taha e rua ki te 6.
y=\frac{18-6x}{6}
Mā te whakawehe ki te 6 ka wetekia te whakareanga ki te 6.
y=3-x
Whakawehe 18-6x ki te 6.
