Answer 1

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

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