0.85x-0.75x<50
Tangohia te 0.75x mai i ngā taha e rua.
0.1x<50
Pahekotia te 0.85x me -0.75x, ka 0.1x.
x<\frac{50}{0.1}
Whakawehea ngā taha e rua ki te 0.1. I te mea he tōrunga te 0.1, kāore e huri te ahunga koreōrite.
x<500
Whakarohaina te \frac{50}{0.1} mā te whakarea i te taurunga me te tauraro ki te 10. Ka whakawehea he tau ki te tahi, hua ai ko ia anō.
