Question

Допоможіть будь ласка 2х-3/8 = 15/4

Answer 1

Ответ:

х = 33/16

Пошаговое объяснение:

$2x - \frac{3}{8} = \frac{15}{4}$

$2x = \frac{15}{4} + \frac{3}{8}$

$2x = \frac{33}{8}$

$x = \frac{33}{8} : 2\\\\x = \frac{33}{8} * \frac{1}{2} = \frac{33}{16}$

проверка

$2 * \frac{33}{16} - \frac{3}{8} = \frac{15}{4} \\\\\frac{66}{16} - \frac{3}{8} = \frac{15}{4} \\\\\frac{60}{16} = \frac{15}{4} \\\\\frac{15}{4} = \frac{15}{4}$
