Question

15/17-(b - 3/17)=6/17
b=?

Answer 1

Ответ:

b-3/17 = 15/17 - 6/17

b-3/17 = 9/17

b = 9/17 + 3/17

b = 12/17

Answer 2

Ответ:

$\frac{12}{17}$

Пошаговое объяснение:

$\frac{15}{17} - (b - \frac{3}{17}) = \frac{6}{17}\\\\b - \frac{3}{17} = \frac{15}{17} - \frac{6}{17}\\\\b - \frac{3}{17} = \frac{9}{17}\\\\b = \frac{9}{17} + \frac{3}{17} = \frac{12}{17}$
