Hello, thank you very much for helping my previous problem.

I have another problem. I tried simplifying the solutions of a
simultaneous difference equations; i.e. I typed

Simplify[-1-5*(3^x)+(31/63)*(2^(2+x))*(5^(1+x))-((53*(10^x))/63),x "set
of" Reals]

Yet, Mathematica does not simplify the expressions. I know the above
expression can be written as:

If you know how to simplify the above expression, could you let me know?
Thank you very much in advance.
