Five times a number is divided by 7 more than that number. If the result is -8, then what was the original number?

Let the original number be called x. We can rewrite the original problem as:

 

(five times a number) is divided by (7 more than that number) = -8

5x/(x + 7) = -8

5x = -8(x + 7)

5x = -8x - 56

13x = -56

x = -56/13
