Kua tāruatia ki te papatopenga
\frac{2}{7}x-4=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{2}{7}x=y+4
Me tāpiri te 4 ki ngā taha e rua.
\frac{\frac{2}{7}x}{\frac{2}{7}}=\frac{y+4}{\frac{2}{7}}
Whakawehea ngā taha e rua o te whārite ki te \frac{2}{7}, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.
x=\frac{y+4}{\frac{2}{7}}
Mā te whakawehe ki te \frac{2}{7} ka wetekia te whakareanga ki te \frac{2}{7}.
x=\frac{7y}{2}+14
Whakawehe y+4 ki te \frac{2}{7} mā te whakarea y+4 ki te tau huripoki o \frac{2}{7}.
