Kua tāruatia ki te papatopenga
5x=25-2y
Tangohia te 2y mai i ngā taha e rua.
\frac{5x}{5}=\frac{25-2y}{5}
Whakawehea ngā taha e rua ki te 5.
x=\frac{25-2y}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
x=-\frac{2y}{5}+5
Whakawehe 25-2y ki te 5.
2y=25-5x
Tangohia te 5x mai i ngā taha e rua.
\frac{2y}{2}=\frac{25-5x}{2}
Whakawehea ngā taha e rua ki te 2.
y=\frac{25-5x}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
