Answer:
x = - 27/8

Step-by-step explanation:
¹²⁾x/5 - ¹²⁾1/5 = ²⁰⁾x/3 + ¹⁵⁾1/4
12x - 12 = 20x + 15
- 12 - 15 = 20x - 12x
- 27 = 8x
x = - 27/8

 
        
             
        
        
        
15^2x is 225x.  So, we have 225x-3=245.  Adding three to both sides, we get 225x=248.  Dividing by 225, we have x=248/225.
