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