Question

resolver la ecuacion 2/7x-9/4=5/3

Answer 1

Explicación paso a paso:

$\frac{2}{7} x - \frac{9}{4} = \frac{5}{3} \\ \\ \frac{2}{7} x = \frac{5}{3} + \frac{9}{4} \\ \\ \frac{2}{7} x = \frac{20 + 27}{12} \\ \\ \frac{2}{7} x = \frac{47}{12} \\ \\ x = \frac{47}{12} \div \frac{2}{7} \\ \\ x = \frac{329}{24} \\ \\ comprobación \\ \frac{2}{7} \times \frac{329}{24} - \frac{9}{4} = \frac{5}{3} \\ \\ \frac{658}{168} - \frac{9}{4} = \frac{5}{3} \\ \\ \frac{658 - 378}{168} = \frac{5}{3} \\ \\ \frac{280}{168} = \frac{5}{3} \\ \\ \frac{5}{3} = \frac{5}{3}$
