2x=10-5y
Tangohia te 5y mai i ngā taha e rua.
\frac{2x}{2}=\frac{10-5y}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{10-5y}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=-\frac{5y}{2}+5
Whakawehe 10-5y ki te 2.
5y=10-2x
Tangohia te 2x mai i ngā taha e rua.
\frac{5y}{5}=\frac{10-2x}{5}
Whakawehea ngā taha e rua ki te 5.
y=\frac{10-2x}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
y=-\frac{2x}{5}+2
Whakawehe 10-2x ki te 5.
