Kua tāruatia ki te papatopenga
40x+30=Y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
40x=Y-30
Tangohia te 30 mai i ngā taha e rua.
\frac{40x}{40}=\frac{Y-30}{40}
Whakawehea ngā taha e rua ki te 40.
x=\frac{Y-30}{40}
Mā te whakawehe ki te 40 ka wetekia te whakareanga ki te 40.
x=\frac{Y}{40}-\frac{3}{4}
Whakawehe Y-30 ki te 40.
