1.25x=12000-2100
Tangohia te 2100 mai i ngā taha e rua.
1.25x=9900
Tangohia te 2100 i te 12000, ka 9900.
x=\frac{9900}{1.25}
Whakawehea ngā taha e rua ki te 1.25.
x=\frac{990000}{125}
Whakarohaina te \frac{9900}{1.25} mā te whakarea i te taurunga me te tauraro ki te 100.
x=7920
Whakawehea te 990000 ki te 125, kia riro ko 7920.
