Kua tāruatia ki te papatopenga
-8x+4=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-8x=y-4
Tangohia te 4 mai i ngā taha e rua.
\frac{-8x}{-8}=\frac{y-4}{-8}
Whakawehea ngā taha e rua ki te -8.
x=\frac{y-4}{-8}
Mā te whakawehe ki te -8 ka wetekia te whakareanga ki te -8.
x=-\frac{y}{8}+\frac{1}{2}
Whakawehe y-4 ki te -8.
