Answer 2

$\frac{x + 3}{7} - \frac{2x - 5}{3} = \frac{3x - 5}{5} - 25 \\ \frac{3x + 9 - (14x - 35)}{21} = \frac{3x - 5 - 125}{5} \\ \frac{3x + 9 - 14x + 35}{21} = \frac{3x - 130}{5} \\ \frac{ - 11x + 44}{21} = \frac{3x - 130}{5} \\ - 55x + 220 = 63x - 2730 \\ - 63 x- 55 x = - 2730 - 220 \\ 118x = 2950 \\ x = 25$
