Question

2x/5 -2/1 = x/4 +4/1 Qual o resultado ?

Answer 1

2x/5 -2/1 = x/4 +4/1
2x - x = 2 + 4   mmc = 20
 5    4
 8x - 5x = 40 + 80
     3x = 120
       x = 40

Answer 2

$\frac{2x}{5} - \frac{2}{1} - \frac{x}{4} - \frac{4}{1} = 0$

MMC = 20

$\frac{8x - 40 - 5x - 80}{20} = 0 3x -120 = 0 => x = \frac{120}{3} => x = 40$
