Combine like terms to simplify the expression. 5x + 4 + 2x + 5 will give 20 if you can answer my next question

5x + 4 + 2x + 5

First add the like terms.

You will get this: 7x + 9

And these can't be simplified anymore because they do not both go into the same multiple.

So your answer will be:

7x + 9
