Question

A number is multiplied by 20, and that product is added to 5. The sum is equal to the product of 5 and 13.

Answer 1

x = 3

Explanation:

First, you will pick the first equation :

(x*20)

Then the next,

(x*20) + 5

Then the last equation,

(x*20) + 5 = 5*13

Then you solve

20x + 5 = 65

20x = 65 - 5

20x = 60

20x/20 = 60/20

x = 3
