Answer:
z<-2 or z<1
Step-by-step explanation:
The compound inequality to be solved is
5z+3<-7 or -2z-6>-8
![\implies \:5z-8 + 6](https://tex.z-dn.net/?f=%20%5Cimplies%20%5C%3A5z%3C-7%20-%203%20%5C%3A%20%20or%20-2z%3E-8%20%2B%206)
![\implies \:5z-2](https://tex.z-dn.net/?f=%5Cimplies%20%5C%3A5z%3C-10%20%20%20%5C%3A%20%20or%20-2z%3E-2)
![\implies \: \frac{5z}{5} < \frac{ - 10}{5} \: or \frac{-2z}{-2} > \frac{ - 2}{ - 2}](https://tex.z-dn.net/?f=%5Cimplies%20%5C%3A%20%5Cfrac%7B5z%7D%7B5%7D%20%3C%20%5Cfrac%7B%20-%2010%7D%7B5%7D%20%20%5C%3A%20%20or%20%20%5Cfrac%7B-2z%7D%7B-2%7D%20%3E%20%5Cfrac%7B%20-%202%7D%7B%20-%202%7D%20)
Simplifying we get,
z<-2 or z<1
NB: the inequality sign at the right side of or has changed because we have divided through by -2
