Kua tāruatia ki te papatopenga
0.7x=13902
Pahekotia te x me -x\times 0.3, ka 0.7x.
x=\frac{13902}{0.7}
Whakawehea ngā taha e rua ki te 0.7.
x=\frac{139020}{7}
Whakarohaina te \frac{13902}{0.7} mā te whakarea i te taurunga me te tauraro ki te 10.
x=19860
Whakawehea te 139020 ki te 7, kia riro ko 19860.
