Kua tāruatia ki te papatopenga
21a=1-x
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{21a}{21}=\frac{1-x}{21}
Whakawehea ngā taha e rua ki te 21.
a=\frac{1-x}{21}
Mā te whakawehe ki te 21 ka wetekia te whakareanga ki te 21.
-x=21a-1
Tangohia te 1 mai i ngā taha e rua.
\frac{-x}{-1}=\frac{21a-1}{-1}
Whakawehea ngā taha e rua ki te -1.
x=\frac{21a-1}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
x=1-21a
Whakawehe 21a-1 ki te -1.
