Kua tāruatia ki te papatopenga
0.8x=100+300
Me tāpiri te 300 ki ngā taha e rua.
0.8x=400
Tāpirihia te 100 ki te 300, ka 400.
x=\frac{400}{0.8}
Whakawehea ngā taha e rua ki te 0.8.
x=\frac{4000}{8}
Whakarohaina te \frac{400}{0.8} mā te whakarea i te taurunga me te tauraro ki te 10.
x=500
Whakawehea te 4000 ki te 8, kia riro ko 500.
