x x + 2 x x
25 - 5 + 26 25 - 7*5 + 1 x
----------------- + -------------- <= 2*5 - 24
x x
5 - 1 5 - 7
$$\frac{\left(25^{x} - 5^{x + 2}\right) + 26}{5^{x} - 1} + \frac{\left(25^{x} - 7 \cdot 5^{x}\right) + 1}{5^{x} - 7} \leq 2 \cdot 5^{x} - 24$$
(25^x - 5^(x + 2) + 26)/(5^x - 1) + (25^x - 7*5^x + 1)/(5^x - 7) <= 2*5^x - 24
