Whakaoti mō b
b\leq -6
Tohaina
Kua tāruatia ki te papatopenga
-12b\geq 19+53
Me tāpiri te 53 ki ngā taha e rua.
-12b\geq 72
Tāpirihia te 19 ki te 53, ka 72.
b\leq \frac{72}{-12}
Whakawehea ngā taha e rua ki te -12. I te mea he tōraro a -12, ka huri te ahunga koreōrite.
b\leq -6
Whakawehea te 72 ki te -12, kia riro ko -6.
