RESOLUCIÓN:

$\frac{3x + 1}{7} - \frac{2 - 4x}{3} = \frac{ - 5x - 4}{14} + \frac{7x}{6} \\ \frac{3(3x + 1) - 7(2 - 4x)}{7 \times 3} = \frac{6( - 5x - 4) + 14(7x)}{14 \times 6} \\ \frac{9x + 3 - 14 + 28x}{21} = \frac{ - 30x - 24 + 98x}{84} \\ \frac{37x - 11}{21} = \frac{68x - 24}{84} \\ 84(37x - 11) = 21(68x - 24) \\ 3108x - 924 = 1428x - 504 \\ 3108x - 1428x = - 504 + 924 \\ 1680x = 420 \\ x = \frac{420}{1680} \\ x = 0.25$

RESPUESTA:

$0.25$
