Answer: [tex]z<1.25[/tex]
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
Add 8.2 to both sides of the inequality. Then, you obtain:
[tex]-1.2z-8.2+8.2>-9.7+8.2\\-1.2z>-1.5[/tex]
Now you must divide both sides by -1.2, as you can see below:
[tex]\frac{-1.2z}{-1.2}>\frac{-1.5}{-1.2}[/tex]
(The direction of the sign will change).
Therefore, you obtain the following solution:
[tex]z<1.25[/tex]
