Answer 1

$7) \: \: - 8x + 5.2a + 3x + 5a = 10.2a- 5x \\ 8) \: \: 5a - 9.2m + 7a + 15m = 12a + 5.8m \\ 9) \: \: \frac{2}{7} x - \frac{4}{9} y - \frac{5}{14} x + \frac{2}{3} y = \frac{4}{14} x - \frac{4}{9} y - \frac{5}{14} x + \frac{6}{9} y = - \frac{1}{14} x + \frac{2}{9} y$

$10) \: \: - 6a + 5a - x + 4x = 3x - a \\ 11) \: \: 23x - 23 + 40 + 4x = 27x + 17 \\ 12) \: \: 4x - 2a + 6x - 3a + 4 = 10x - 5a + 4$
