y=5/3x
this is because f(x)=x is one of (identity function) the 12 basic functions and when you multiply it it will shift it on the y axis 
If you were to do y=x+5/3 it would make a horizontal shift to the left 5/3
So the unit your on is mostly about knowing the number located in the function that will make the graph shift different ways
 
        
             
        
        
        
I hope this helps you

9 (x-18)=3x-18
9x-9.18=3x-18
9x-3x=9.18-18
6x=8.18
x=8.3
x= 24
