Kua tāruatia ki te papatopenga
\frac{5}{3}x=y-7
Tangohia te 7 mai i ngā taha e rua.
\frac{\frac{5}{3}x}{\frac{5}{3}}=\frac{y-7}{\frac{5}{3}}
Whakawehea ngā taha e rua o te whārite ki te \frac{5}{3}, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.
x=\frac{y-7}{\frac{5}{3}}
Mā te whakawehe ki te \frac{5}{3} ka wetekia te whakareanga ki te \frac{5}{3}.
x=\frac{3y-21}{5}
Whakawehe y-7 ki te \frac{5}{3} mā te whakarea y-7 ki te tau huripoki o \frac{5}{3}.
y=\frac{5}{3}x+7
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
