Answer:

$2x + 6$

Step-by-step explanation:

$7 - (2x + 1) + 4x$

Distribute the negative inside 2x+1

$7 - 2x - 1 + 4x$

Remind that negative multiply negative must equal positive.

variables cannot sum/add/subtract with constants.

They must be the same terms.

$4x - 2x - 1 + 7 \\ 2x + 6$

Therefore, our answer is 2x+6
