Kua tāruatia ki te papatopenga
2x=2280-y
Tangohia te y mai i ngā taha e rua.
\frac{2x}{2}=\frac{2280-y}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{2280-y}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=-\frac{y}{2}+1140
Whakawehe 2280-y ki te 2.
y=2280-2x
Tangohia te 2x mai i ngā taha e rua.
