Kua tāruatia ki te papatopenga
d=10-5y
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te 2-y.
10-5y=d
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-5y=d-10
Tangohia te 10 mai i ngā taha e rua.
\frac{-5y}{-5}=\frac{d-10}{-5}
Whakawehea ngā taha e rua ki te -5.
y=\frac{d-10}{-5}
Mā te whakawehe ki te -5 ka wetekia te whakareanga ki te -5.
y=-\frac{d}{5}+2
Whakawehe d-10 ki te -5.
d=10-5y
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te 2-y.
