Answer 1

$x - 3( \frac{2x + 1}{2} ) = 3( \frac{3x + 9}{3} + 2 - x) - \frac{x}{2} \\ x - \frac{6x - 3}{2} = \frac{3(3x + 9)}{3} + 6 - 3x - \frac{x}{2} \\ \frac{2x - 6x - 3}{2} = 3x + 9 + 6 - 3x - \frac{x}{2} \\ \frac{ - 4x - 3}{2} = 15 - \frac{x}{2} \\ \frac{ - 4x - 3}{2} = \frac{30 - x}{2} \\ - 4x - 3 = 30 - x \\ - 3x = 33 \\ x = \frac{33}{ - 3} \\ x = - 11$
