Question

Add the two expressions. -4.2 +3 and 2.5x - 6

Answer 1

For this case we have the following expressions:

`-4.2 +3\\2.5x - 6`

To add both expressions, what we must do is add similar terms.

We have then:

`2.5x + (-6-4.2 + 3)`

Rewriting we have:

`2.5x-7.2`

Answer:

The sum of both expressions is given by:

`2.5x-7.2`
