Question

(×-5)/10+(1-2×)/5=(3-×)/4me ajuda por favor ​

Answer 1

$\frac{(x - 5)}{10} + \frac{(1 - 2x)}{5} = \frac{3 - x}{4} \\ \frac{2(x - 5) + 4(1 - 2x) = 5(3 - x)}{20} \\ 2(x - 5) + 4(1 - 2x) = 5(3 - x)$

$2x - 1 + 4 - 8x = 15 - 5x \\ 2x - 8x + 5x = 15 + 1 - 4 \\ - x = 12 \times ( - 1) \\ x = - 12$
