Kua tāruatia ki te papatopenga
50-2x=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-2x=y-50
Tangohia te 50 mai i ngā taha e rua.
\frac{-2x}{-2}=\frac{y-50}{-2}
Whakawehea ngā taha e rua ki te -2.
x=\frac{y-50}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
x=-\frac{y}{2}+25
Whakawehe y-50 ki te -2.
