Answer 1

$\frac{2x - 3}{3} - \frac{x + 2}{4} = \frac{5}{12 } \\ 4(2x - 3) - 3(x + 2) = 5 \\ 8x - 12 - 3x - 6 = 5 \\ 5x - 18 = 5 \\ 5x = 5 + 18 \\ 5x = 2 3 \\ x = \frac{23}{5 } \\ x = 4.1$

$\frac{2}{3} + \frac{ x}{4} + \frac{1 - x}{6} = \frac{5x}{12} - 1 \\ 8 + 3x + 2(1 - x) = 5x - 12 \\ 8 + 3x + 2 - 2x = 5x - 12 \\ 10 + x = 5x - 12 \\ x - 5 = - 12 - 10 \\ - 4x = - 22 \\ x = \frac{11}{2} \\ x = 5.5$

$\frac{3}{4} + \frac{x}{2} - \frac{5 - x}{3} = 1 \\ 9 + 6x - 4(5 - x) = 12 \\ 9 + 6x - 20 + 4x = 12 \\ - 11 + 10x = 12 \\ 10x = 12 + 11 \\ 10x = 23 \\ x = \frac{23}{20} \\ x = 2.3$
