resolva pfv me ajude

Answer 1

A) $\frac{x}{2} - \frac{x}{4} = \frac{1}{2}$
     $\frac{x}{4} = \frac{1}{2}$
     $\frac{2}{1} = x$

B)  $\frac{x}{4} - \frac{x}{2} = 5 - 7$
      $\frac{-2x}{4} = -2$
      - 2x = - 8
          x = -4

C)  $\frac{x}{3} - \frac{2x}{1} = - 4$
     - 5x = - 12
         x = $\frac{12}{5}$

D)  $\frac{5x}{12} - \frac{x}{3} = -1$
      x = - 12
