Step-by-step explanation:
![\frac{1}{6} + \frac{2}{12} + \frac{3}{4} + \frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B6%7D%20%20%2B%20%20%5Cfrac%7B2%7D%7B12%7D%20%20%2B%20%20%5Cfrac%7B3%7D%7B4%7D%20%20%2B%20%20%5Cfrac%7B1%7D%7B2%7D%20)
![\frac{2}{12} + \frac{2}{12} + \frac{9}{12} + \frac{6}{12}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B12%7D%20%20%2B%20%20%5Cfrac%7B2%7D%7B12%7D%20%20%2B%20%20%5Cfrac%7B9%7D%7B12%7D%20%20%2B%20%20%5Cfrac%7B6%7D%7B12%7D%20)
![\frac{19}{12}](https://tex.z-dn.net/?f=%20%5Cfrac%7B19%7D%7B12%7D%20)
I believe the answer would be -2 and -11 hope this helped!
Da number is n
2n-(n/2)≥12
times both sides by 2
4n-n≥24
3n≥24
divide both sides by 3
n≥8
