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