Question

-4 3/8х +6х-(х-2/8х)​

Answer 1

Ответ:

$\frac{7}{8} x$

Пошаговое объяснение:

$- 4 \frac{3}{8} x + 6x - (x - \frac{2}{8}x) = - \frac{35}{8} x + 6x - (x - \frac{1}{4} x) = - \frac{35}{8} x + 6x - \frac{3}{4} x = - \frac{35x}{8} + \frac{6x}{1} - \frac{3x}{4} = - \frac{35x}{8} + \frac{8 \times 6x}{8 \times 1} - \frac{2 \times 3x}{2 \times 4} = - \frac{35x}{8} + \frac{48x}{8} - \frac{6x}{8} = \frac{ - 35x + 48x - 6x}{8} = \frac{7x}{8} = \frac{7}{8} x$
