Question

2 9/14*х-1 17/21*х=1 1/9

Answer 1

Ответ:

$2 \frac{9}{14} \times x - 1 \frac{17}{21} \times x = 1 \frac{1}{9} \\ \frac{37}{14} \times x - \frac{38}{21} \times x = \frac{10}{9} \\ \frac{5}{6} \times x = \frac{10}{9} \\ x = \frac{10}{9} \div \frac{5}{6} \\ x = \frac{10}{9} \times \frac{6}{5} \\ x = \frac{4}{3} \\ x = 1 \frac{1}{3}$
