Kua tāruatia ki te papatopenga
4b-16=r
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te b-4.
4b=r+16
Me tāpiri te 16 ki ngā taha e rua.
\frac{4b}{4}=\frac{r+16}{4}
Whakawehea ngā taha e rua ki te 4.
b=\frac{r+16}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
b=\frac{r}{4}+4
Whakawehe r+16 ki te 4.
4b-16=r
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te b-4.
r=4b-16
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
