Answer 1

$\frac{11}{12} x - \frac{2}{3} = \frac{1}{2} - \frac{3}{4} x \\ 12( \frac{11}{12} x - \frac{2}{3} ) = 12 \times ( \frac{1}{2} - \frac{3}{4} x) \\ 11x - 8 = - 6 - 9x \\ 11x + 9x = - 6 + 8 \\ 20x = 2 \\ x = \frac{1}{10} \\ x = 0.1$

$12( \frac{x}{3} + 5) = 12( \frac{x}{4} + 3 ) \\ 4x + 60 = 3x + 36 \\ 4x - 3x = 36 - 60 \\ x = - 24$
