Question

2/3-(2/9+х)=1/3 помогите пж!!!!​

Answer 1

Ответ:

$\frac{2}{3} - ( \frac{2}{9} + x) = \frac{1}{3} \\ \frac{2}{3} - \frac{2}{9} - x = \frac{1}{3} \\ \frac{4}{9} - x = \frac{1}{3} \\ - x = \frac{1}{3} - \frac{4}{9} \\ - x = - \frac{1}{9} \\ x = \frac{1}{9}$

Answer 2

Ответ:

$\frac{2}{3} - ( \frac{2}{9} + x) = \frac{1}{3} \\ \frac{2}{3} - \frac{2 + 9x}{9} = \frac{1}{3} \\ \frac{6 - 2 -9 x}{9} = \frac{3}{9} \\ 4-9x = 3 \\ x =\frac{1}{9}$
