Kua tāruatia ki te papatopenga
y=\frac{1}{5}x+\frac{2}{5}
Whakawehea ia wā o x+2 ki te 5, kia riro ko \frac{1}{5}x+\frac{2}{5}.
\frac{1}{5}x+\frac{2}{5}=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{1}{5}x=y-\frac{2}{5}
Tangohia te \frac{2}{5} mai i ngā taha e rua.
\frac{\frac{1}{5}x}{\frac{1}{5}}=\frac{y-\frac{2}{5}}{\frac{1}{5}}
Me whakarea ngā taha e rua ki te 5.
x=\frac{y-\frac{2}{5}}{\frac{1}{5}}
Mā te whakawehe ki te \frac{1}{5} ka wetekia te whakareanga ki te \frac{1}{5}.
x=5y-2
Whakawehe y-\frac{2}{5} ki te \frac{1}{5} mā te whakarea y-\frac{2}{5} ki te tau huripoki o \frac{1}{5}.
y=\frac{1}{5}x+\frac{2}{5}
Whakawehea ia wā o x+2 ki te 5, kia riro ko \frac{1}{5}x+\frac{2}{5}.
