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