Kua tāruatia ki te papatopenga
-3x-1=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-3x=y+1
Me tāpiri te 1 ki ngā taha e rua.
\frac{-3x}{-3}=\frac{y+1}{-3}
Whakawehea ngā taha e rua ki te -3.
x=\frac{y+1}{-3}
Mā te whakawehe ki te -3 ka wetekia te whakareanga ki te -3.
x=\frac{-y-1}{3}
Whakawehe y+1 ki te -3.
