Kua tāruatia ki te papatopenga
180+75x=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
75x=y-180
Tangohia te 180 mai i ngā taha e rua.
\frac{75x}{75}=\frac{y-180}{75}
Whakawehea ngā taha e rua ki te 75.
x=\frac{y-180}{75}
Mā te whakawehe ki te 75 ka wetekia te whakareanga ki te 75.
x=\frac{y}{75}-\frac{12}{5}
Whakawehe y-180 ki te 75.
