Answer:

I will do a step by step explanation to help you.

First, subtract 16 from 31 so you can simplify what you need to find. We will call the unknown number X. So 5x = 15

15/5 = 3 so X = 3

Lets plug in X

3 x 5 + 16 = 31

Makes sense!

Hope this helps

The sum of five times a number and 16 which gives 31 can be obtained using a system of mathematical expression. Hence, the number is 3

Let the number = x :

5x + 16 = 31

5x = 31 - 16

5x = 15

x = 15/5

x = 3

Therefore, the Number is 3.
