7.5x>100-10
Tangohia te 10 mai i ngā taha e rua.
7.5x>90
Tangohia te 10 i te 100, ka 90.
x>\frac{90}{7.5}
Whakawehea ngā taha e rua ki te 7.5. I te mea he tōrunga te 7.5, kāore e huri te ahunga koreōrite.
x>\frac{900}{75}
Whakarohaina te \frac{90}{7.5} mā te whakarea i te taurunga me te tauraro ki te 10.
x>12
Whakawehea te 900 ki te 75, kia riro ko 12.
