Answer 1

           $\frac{x}{4} + \frac{3x-2}{2} = \frac{x-3}{2} \\ \\ \frac{x}{4} + \frac{2(3x-2)}{2.2} = \frac{2(x-3)}{2.2} \\ \\ x+2(3x-2) = 2(x-3) \\ \\ x+6x-4=2x-6 \\ \\ x+6x-2x=-6+4 \\ \\ 5x=-2 \\ \\ x= \frac{-2}{5} \\ \\ x=- \frac{2}{5}$

Answer 2

$\dfrac{x}{4} + \dfrac{3x - 2}{2} = \dfrac{x - 3}{2}$

MMC do primeiro termo, 4,  2 = 4

$\dfrac{x + 6x - 4}{4} = \dfrac{x - 3}{2} \\ \\ \\ \dfrac{7x - 4}{4} = \dfrac{x - 3}{2} \\ \\ \\ 2(7x - 4) = 4(x - 3) \\ \\ 14x - 8 = 4x - 12 \\ \\ 14x - 4x = -12 + 8 \\ \\ 10x = -4 \\ \\ x = \dfrac{-4}{10} \\ \\ \\ =\ \textgreater \ x = -\dfrac{2}{5}$
