Answer 2

Answer:
`z<1.25`

Explanation:

To solve this problem you must apply the proccedure shown below:

Add 8.2 to both sides of the inequality. Then, you obtain:

`-1.2z-8.2+8.2>-9.7+8.2\\-1.2z>-1.5`

Now you must divide both sides by -1.2, as you can see below:

`(-1.2z)/(-1.2)>(-1.5)/(-1.2)`

(The direction of the sign will change).

Therefore, you obtain the following solution:

`z<1.25`
