Kua tāruatia ki te papatopenga
-5x+2=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-5x=y-2
Tangohia te 2 mai i ngā taha e rua.
\frac{-5x}{-5}=\frac{y-2}{-5}
Whakawehea ngā taha e rua ki te -5.
x=\frac{y-2}{-5}
Mā te whakawehe ki te -5 ka wetekia te whakareanga ki te -5.
x=\frac{2-y}{5}
Whakawehe y-2 ki te -5.
