Kua tāruatia ki te papatopenga
0.2-0.05b\leq 22
Pahekotia te -0.4b me 0.35b, ka -0.05b.
-0.05b\leq 22-0.2
Tangohia te 0.2 mai i ngā taha e rua.
-0.05b\leq 21.8
Tangohia te 0.2 i te 22, ka 21.8.
b\geq \frac{21.8}{-0.05}
Whakawehea ngā taha e rua ki te -0.05. I te mea he tōraro a -0.05, ka huri te ahunga koreōrite.
b\geq \frac{2180}{-5}
Whakarohaina te \frac{21.8}{-0.05} mā te whakarea i te taurunga me te tauraro ki te 100.
b\geq -436
Whakawehea te 2180 ki te -5, kia riro ko -436.
