Resolver las ecuaciones
$\frac{3}{4} x - \frac{1}{2} = \frac{5}{8}$

$x - \frac{1}{7} = \frac{2}{5}$
​

Answer 1

Respuesta:

$\frac{3}{4} x - \frac{1}{2} = \frac{5}{8}$

$\frac{3}{4} x = \frac{5}{8} + \frac{1}{2}$

$\frac{3}{4} x = \frac{5 + 4}{8}$

$\frac{3}{4} x = \frac{9}{8}$

$3x = \frac{9}{8} \times 4$

$3x = \frac{9}{2}$

$x = \frac{9}{2} \div 3$

$x = \frac{3}{2}$

____________________________________________

$x - \frac{1}{7} = \frac{2}{5}$

$x = \frac{2}{5} + \frac{1}{7}$

$x = \frac{14 + 5}{35}$

$x = \frac{19}{35}$
