Tohaina
Kua tāruatia ki te papatopenga
0.08x-0.05x>13.8
Tangohia te 0.05x mai i ngā taha e rua.
0.03x>13.8
Pahekotia te 0.08x me -0.05x, ka 0.03x.
x>\frac{13.8}{0.03}
Whakawehea ngā taha e rua ki te 0.03. I te mea he tōrunga te 0.03, kāore e huri te ahunga koreōrite.
x>\frac{1380}{3}
Whakarohaina te \frac{13.8}{0.03} mā te whakarea i te taurunga me te tauraro ki te 100.
x>460
Whakawehea te 1380 ki te 3, kia riro ko 460.
