Question

Me ayudan plss es para mañana​

Answer 1

Respuesta:

$\frac{3}{x + 5} = \frac{1}{2x - 1} \\ 3(2x - 1) = 1(x + 5) \\ 6x - 3 = x + 5 \\ 6x - x = 5 + 3 \\ 5x = 8 \\ x = \frac{8}{5}$

Comprobación

$\frac{3}{x + 5} = \frac{1}{2x - 1} \\ \frac{3}{ \frac{8}{5} + \frac{25}{5} } = \frac{1}{2 \frac{8}{5} - \frac{5}{5} } \\ \frac{ \frac{3}{1} }{ \frac{33}{5} } = \frac{ \frac{1}{1} }{ \frac{11}{5} } \\ \frac{15}{33} = \frac{5}{11} \\ \frac{5}{11} = \frac{5}{11}$
