Just to clarify for others Q should be

5^x - 5^[x-3] = 124 * 5^y

=> 5^x - [5^x/5^3] = 124*5^y

=> 5^x[1 - 1/125] = 124*5^y

=> [5^x * 124]/125 = 124*5^y

=> 5^[x-3]*124 = 124*5^y

so, y = x-3

Sorry how did you get this ,can u break it a bit further please?

=> 5^x[1 - 1/125] = 124*5^y

=> [5^x * 124]/125 = 124*5^y

5^x[1 - 1/125] became [5^x * 124]/125

Thanks
