Answer: The answer is 7 ( x + 3 ).

Step-by-step explanation:

So we are given in word-form this equation:

seven times the sum of a number and three

We can rewrite this as:

7 times ( number + 3)

This number can be rewritten as a variable. Take any variable of your pick. I'll use x because that's one of the most used variables.

7 ( x + 3 )

There you go! Finished.
