Answer:
4w + 7 = 5
Step-by-step explanation:
"sum" means addition (+), so we're to add <u>two items</u>:
<u>item 1 to be added</u>
<em>"4times a number"</em> means multiplication(x) of 4 and w(because w stands for the unknown number).
Therefore, 4 x w = 4w
<u>item 2 to be added</u>
This is the number 7
<u>The sum</u>
4w + 7
Now, the sum, equals(=) the number 5, therefore answer:
4w + 7 = 5
