Answer:

4w + 7 = 5

Explanation:

"sum" means addition (+), so we're to add two items:

item 1 to be added

"4times a number" means multiplication(x) of 4 and w(because w stands for the unknown number).

Therefore, 4 x w = 4w

item 2 to be added

This is the number 7

The sum

4w + 7

Now, the sum, equals(=) the number 5, therefore answer:

4w + 7 = 5
