Kua tāruatia ki te papatopenga
1.4x=2450\times 0.2
Pahekotia te 0.4x me x, ka 1.4x.
1.4x=490
Whakareatia te 2450 ki te 0.2, ka 490.
x=\frac{490}{1.4}
Whakawehea ngā taha e rua ki te 1.4.
x=\frac{4900}{14}
Whakarohaina te \frac{490}{1.4} mā te whakarea i te taurunga me te tauraro ki te 10.
x=350
Whakawehea te 4900 ki te 14, kia riro ko 350.
