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