Answer:
The property used in the simplification is: Distributive Property.
Step-by-step explanation:
" The distributive property is used to combine the two terms that had the same variable. The distributive property is the key to combining expressions with like terms.
Terms are like terms when they have the exact same variables with the exact same exponents" .
Hence, the property used in the simplification of this expression is a distributive property.

Answer: 
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:

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

(The direction of the sign will change).
Therefore, you obtain the following solution:
