Kua tāruatia ki te papatopenga
-2x-3=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-2x=y+3
Me tāpiri te 3 ki ngā taha e rua.
\frac{-2x}{-2}=\frac{y+3}{-2}
Whakawehea ngā taha e rua ki te -2.
x=\frac{y+3}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
x=\frac{-y-3}{2}
Whakawehe y+3 ki te -2.
