Kua tāruatia ki te papatopenga
2y=41200-x
Tangohia te x mai i ngā taha e rua.
\frac{2y}{2}=\frac{41200-x}{2}
Whakawehea ngā taha e rua ki te 2.
y=\frac{41200-x}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
y=-\frac{x}{2}+20600
Whakawehe 41200-x ki te 2.
x=41200-2y
Tangohia te 2y mai i ngā taha e rua.
