Kua tāruatia ki te papatopenga
\frac{2}{5}x-3=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{2}{5}x=y+3
Me tāpiri te 3 ki ngā taha e rua.
\frac{\frac{2}{5}x}{\frac{2}{5}}=\frac{y+3}{\frac{2}{5}}
Whakawehea ngā taha e rua o te whārite ki te \frac{2}{5}, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.
x=\frac{y+3}{\frac{2}{5}}
Mā te whakawehe ki te \frac{2}{5} ka wetekia te whakareanga ki te \frac{2}{5}.
x=\frac{5y+15}{2}
Whakawehe y+3 ki te \frac{2}{5} mā te whakarea y+3 ki te tau huripoki o \frac{2}{5}.
