Question

5/18+(15/18-(x-7/18))=11/18

Answer 1

Ответ:

Пошаговое объяснение:

5/18+(15/18-(x-7/18))=11/18

5/18+(15/18-x+7/18)=11/18

5/18 + 15/18 - x + 7/18 = 11/18

27/18 - x = 11/18

x = 27/18 - 11/18

x = 16/18

x = 8/9

Answer 2

$\frac{15}{18} - (x - \frac{7}{18} ) = \frac{11}{18} - \frac{5}{18} = \frac{6}{18} = \\ \frac{1}{3}$
$x - \frac{7}{18} = \frac{15}{18} - \frac{1}{3} = \frac{15}{18} - \frac{6}{18} = \\ = \frac{9}{18}$
$x = \frac{9}{18} + \frac{7}{18} = \frac{16}{18} = \frac{8}{9}$
