7.4z - 5(-1.6z + 2.4)

Explanation:

The initial expression that we have in this problem is

First of all, we multiply the -5 by all the terms in the brackets. Doing so, we get the following expression:

Now we can combine the like terms, which are the terms having the same variable.

Here the like terms are:

and

-12

Combining the first 2 terms we get

Therefore, the final expression overall is:
