Question

решите уравнение
(x+1/7)-4/7=2/6​

Answer 1

Ответ:

16/21

Пошаговое объяснение:

(х+1/7)-4/7=2/6

х+1/7=2/6+4/7

х+1/7=14/42+24/42

х+1/7=38/42

х=38/42-1/7

х=38/42-6/42

х=32/42

х=16/21

Answer 2

$(x + frac{1}{7} ) - frac{4}{7} = frac{2}{6} \ x + frac{1}{7} - frac{4}{7} = frac{2}{6} \ x + frac{1 - 4}{7} = frac{2}{6} \ x - frac{3}{7} = frac{2}{6} \ x = frac{2}{6} + frac{3}{7} \ x = frac{1}{3} + frac{3}{7} \ x = frac{7 + 9}{21} \ x = frac{16}{21}$
