Question

$\frac{2}{3} x + 5 = 3 + \frac{7}{9} x$
Помогите ​

Answer 1

$\frac{2}{3} x + 5 = 3 + \frac{7}{9} x \\ \\ \frac{7}{9} x - \frac{2}{3} x = 5 - 3 \\ \\ \frac{7}{9} x - \frac{6}{9} x = 2 \\ \\ ( \frac{7}{9} - \frac{6}{9} )x = 2 \\ \\ \frac{1}{9} x = 2 \\ \\ x = 9 \times 2 = 18$

ОТВЕТ: 18

Answer 2

Ответ:

18

Пошаговое объяснение:

$\frac{2}{3}x - \frac{7}{9}x = 3 - 5\\\\\frac{6}{9}x - \frac{7}{9}x = -2\\\\-\frac{1}{9}x = -2\\\\\frac{1}{9}x = 2\\\\x = 2 * 9 = 18$
