Question

X + 1/10 = 2/5 - 2/7 , hallar x​

Answer 1

Respuesta:

$-\frac{2}{35}$

Explicación paso a paso:

$x+\frac{1}{10} =\frac{2}{5} -\frac{2}{7} \\\\x+\frac{1}{10}= \frac{2}{5} -\frac{2}{7}= \frac{14-10}{35}=\frac{4}{35} \\\\x+\frac{1}{10}= \frac{4}{35}\\\\x=\frac{4}{35}-\frac{1}{10} = \frac{2-7}{70} =-\frac{4}{70} =- \frac{2}{35} \\\\x=-\frac{2}{35}$

Espero que te sirva ;)
