Question

resolva as equações:

Answer 1

A)  $\frac{x}{4} - \frac{x}{6} = 3$
      $\frac{3x-2x}{12} =3$
      x = 36

B)  $\frac{3x}{4} - \frac{x}{3} =5$
      $5x = 60$
      x = 12

C)  $\frac{x}{5} - 1 = 9$
      $x-5 =45$
      x = 50

D)  $\frac{x}{3} - 5 =0$
      x - 15 = 0
      x = 15

E)  $\frac{x}{2} + \frac{3x}{5} = 6$
      11x = 60
         x = $\frac{60}{11}$
