Ryan is thinking of a number. When he multiplies this number by 6 and then subtracts 15 from the answer, he ends up with his original number. What number is Ryan thinking of?

Hi there! I'm a dumb idiot. Anyways, how to solve this problem. So we see here that the number that they gave us can be multiplied and subtracted by 15 to get back to the original number. Now, we have to solve for x. The formula is: 6x-15=x. How do we find out for x? Let's look at the factors of 6 and 15. They both have 3. Now, let's see if 3 works. 6x3=18-15=3. I hope this helped! :)
