Question

Resolva a equação abaixo;

a) X/5 - 1/6 = 2/3

b) 2x/4 - 3/8 = 5/3

Answer 1

$a) \frac{x}{5} - \frac{1}{6} = \frac{2}{3}$
6x-5=20
$x= \frac{25}{6}$

$b) \frac{2x}{4} - \frac{3}{8} = \frac{5}{3}$
12x-9=40
$x= \frac{49}{12}$

Answer 2

$A) \frac{x}{5} - \frac{1}{6} = \frac{2}{3}$
$\frac{6x - 5}{30} = \frac{2}{3}$
$18x - 15 = 60$
$18x = 60 + 15$
$18x = 75$
$x = \frac{75}{18}$
$x = \frac{25}{6} = 4,1666...$
$B) \frac{2x}{4} - \frac{3}{8} = \frac{5}{3}$
$\frac{4x - 3}{8} = \frac{5}{3}$
$12x - 9 = 40$
$12x = 40 + 9$
$12x = 49$
$x = \frac{49}{12}$
$x = 4,08333...$
