+(x+3) is just x +3, thus 7+x+3, is just 10+x, since the like-terms are combined.

Hey there!

7 + (x + 3)

= 7 + 1(x + 3)

= 7 + 1(x) + 1(3)

= 7 + 1x + 3

= 1x + 10 which is about x + 10

Therefore, your answer is: [x + 10] or 1x + 10 either of those should work.

Good luck on your assignment and enjoy your day!
