I'm a little confused by your question. 
You said 60-8 = 52 which is true.
Then, you asked 4x = 52 in an integer form
                           x = 52/4
                           x = 13. (Is that what you're asking?)
I'm not sure if this helps, but please comment if you need any help! Hope this helps though! :D
