Kua tāruatia ki te papatopenga
y=\frac{5+3}{5}x-1+2
Whakareatia te 1 ki te 5, ka 5.
y=\frac{8}{5}x-1+2
Tāpirihia te 5 ki te 3, ka 8.
y=\frac{8}{5}x+1
Tāpirihia te -1 ki te 2, ka 1.
\frac{8}{5}x+1=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{8}{5}x=y-1
Tangohia te 1 mai i ngā taha e rua.
\frac{\frac{8}{5}x}{\frac{8}{5}}=\frac{y-1}{\frac{8}{5}}
Whakawehea ngā taha e rua o te whārite ki te \frac{8}{5}, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.
x=\frac{y-1}{\frac{8}{5}}
Mā te whakawehe ki te \frac{8}{5} ka wetekia te whakareanga ki te \frac{8}{5}.
x=\frac{5y-5}{8}
Whakawehe y-1 ki te \frac{8}{5} mā te whakarea y-1 ki te tau huripoki o \frac{8}{5}.
y=\frac{5+3}{5}x-1+2
Whakareatia te 1 ki te 5, ka 5.
y=\frac{8}{5}x-1+2
Tāpirihia te 5 ki te 3, ka 8.
y=\frac{8}{5}x+1
Tāpirihia te -1 ki te 2, ka 1.
