Question

5x sobre 2 - 7x sobre 5 + 4x-5 sobre 2= 8x-5 sobre 5 - 11x-3 sobre 2

Answer 1

RESOLUCIÓN:

$\frac{5x}{2} - \frac{7x}{5} + \frac{4x - 5}{2} = \frac{8x - 5}{5} - \frac{11x - 3}{2} \\ \frac{31x - 25}{10} = \frac{5 - 39x}{10} \\ 31x - 25 = 5 - 39x \\ 31x + 39x = 5 + 25 \\ 70x = 30 \\ x = \frac{70}{30} \\ x = \frac{7}{3}$
