Question

60/90-(6/90 + x) = 300/90​

Answer 1

Ответ:

$x = \frac{41}{15}$

Пошаговое объяснение:

$\frac{60}{90} - ( \frac{6}{90} + x) = \frac{300}{90}$

$\frac{60}{90} - ( \frac{1}{15} + x) = \frac{300}{90}$

$\frac{60}{90} - ( \frac{1}{15} + x) = \frac{10}{3}$

$\frac{60}{90} - \frac{1}{15} - x = \frac{10}{3}$

$\frac{3}{5} - x = \frac{10}{3}$

$- x = \frac{10}{3} - \frac{3}{5}$

$- x = \frac{41}{15}$

$x = \frac{41}{15}$
