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