5 = what percent of 23
5 = x% of 23
5 = (x/100)*23
5 = 23x/100
5*100 = 23x
23x = 5*100
x = 5*100/23
x = 21.739
5 is ≈ 21.739% of 23 
        
             
        
        
        
What you can do is subtract 1x from each side 
Then you subtract 3 from each side
Then it tells you x=2
Always put what you think x is back into the problem and see if it works out
Example on how you do it:
(x+5)=(2x+3)
5=(x+3)
2=x
