Question

resolba a equacao
$\frac{x}{2} + \frac{x}{3} - \frac{x}{4} = 14 =$
​

Answer 1

$\frac{x}{2} + \frac{x}{3} - \frac{x}{4} = 14$

$12( \frac{x}{2} + \frac{x}{3} - \frac{x}{4} ) = 12 \: . \: 14$

$12 \: . \: \frac{x}{2} + 12 \: . \: \frac{x}{3} - 12 \: . \: \frac{x}{4} = 168$

$6x + 4x - 3x = 168$

$10x - 3x = 168$

$7x = 168$

$x = \frac{168}{7}$

$\boxed{x = 24}$

Answer 2

$\frac{x}{2} + \frac{x}{3} - \frac{x}{4} = 14 =$

$\frac{3x+2x}{6} - \frac{x}{4} = 14 =$

$\frac{12x+8x-6x}{24} = 14 =$

12x +8x -6x = 14 • 24

20x -6x = 336

14 x = 336

x= $\frac {336}{14}$
