Question

ПЖ срочно могите!!!!

Облегчите уравнение

$\frac{2}{3}$ * x + $\frac{4}{7}$ = $\frac{2}{3}$

Answer 1

Ответ:

Х= 1/7

Пошаговое объяснение:

$\frac{2}{3} \times x = \frac{2}{3} - \frac{4}{7} \\ \frac{2}{3} \times x = \frac{14}{21} - \frac{12}{21} = \frac{2}{21}$

2/3 * х = 2/21

Х = 2/21 : 2/3

$\frac{2}{21} \div \frac{2}{3} = \frac{2}{21} \times \frac{3}{2} = \frac{3}{21} = \frac{1}{7}$

Х= 1/7
