Question

1/5x + 4 = 5 - 2/7x alguien que me ayude a despejar para x

Answer 1

Respuesta:

1/5x + 4 = 5 - 2/7x

1/5x + 2/7x = 5 - 4

$\frac{1}{5}x+ \frac{2}{7}x = 1\\\\\frac{7x+10x}{35} = 1\\\\\frac{17}{35}x = 1\\ \\x = \frac{1}{\frac{17}{35} }\\\\x = \frac{35}{17}$

comprobación

$\frac{1}{5} (\frac{35}{17}) +4=5-\frac{2}{7} (\frac{35}{17})\\\\\frac{7}{17} + 4 = 5 - \frac{10}{17}\\\\\frac{75}{17} = \frac{75}{17}$
