Kua tāruatia ki te papatopenga
2x+3.5=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
2x=y-3.5
Tangohia te 3.5 mai i ngā taha e rua.
\frac{2x}{2}=\frac{y-3.5}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{y-3.5}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=\frac{y}{2}-\frac{7}{4}
Whakawehe y-3.5 ki te 2.
