Kua tāruatia ki te papatopenga
65+0.8x>109
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa. Ka huri tēnei i te aronga o te tohu.
0.8x>109-65
Tangohia te 65 mai i ngā taha e rua.
0.8x>44
Tangohia te 65 i te 109, ka 44.
x>\frac{44}{0.8}
Whakawehea ngā taha e rua ki te 0.8. I te mea he tōrunga te 0.8, kāore e huri te ahunga koreōrite.
x>\frac{440}{8}
Whakarohaina te \frac{44}{0.8} mā te whakarea i te taurunga me te tauraro ki te 10.
x>55
Whakawehea te 440 ki te 8, kia riro ko 55.
