10x=30-10y
Tangohia te 10y mai i ngā taha e rua.
\frac{10x}{10}=\frac{30-10y}{10}
Whakawehea ngā taha e rua ki te 10.
x=\frac{30-10y}{10}
Mā te whakawehe ki te 10 ka wetekia te whakareanga ki te 10.
x=3-y
Whakawehe 30-10y ki te 10.
10y=30-10x
Tangohia te 10x mai i ngā taha e rua.
\frac{10y}{10}=\frac{30-10x}{10}
Whakawehea ngā taha e rua ki te 10.
y=\frac{30-10x}{10}
Mā te whakawehe ki te 10 ka wetekia te whakareanga ki te 10.
y=3-x
Whakawehe 30-10x ki te 10.
