Question

(6/7x - 1/5) * 1/8 = 1/8
ОТВЕТ НУЖЕН СРОЧНО

Answer 1

Ответ:

( 6 / 7 х - 1/5 ) × 1/8 = 1/8

6/7 х - 1/5 = 1/8 : 1/8

6/7 х - 1/5 = 1

6/7 х = 1 + 1/5

6/7 х = 6/5

х = 6/5 : 6/7

х = 7/5 = 1 2/5

Answer 2

$\displaystyle (\frac{6}{7}x-\frac{1}{5})*\frac{1}{8}=\frac{1}{8}\\\\ \frac{3}{28}x-\frac{1}{40}=\frac{1}{8}\\\\ 30x-7=35\\30x=35+7\\30x=42\\\\ x=\frac{7}{5}=1\frac{2}{5}=1,4$
