Question

x+4 2/7-2 1/3=10 помогите срочно надо

Answer 1

$x + 4\frac{2}{7} - 2 \frac{1}{3} = 10$

$x + \frac{30}{7} - \frac{7}{3} = 10$

$x + \frac{90}{21} - \frac{49}{21} = 10$

$x + \frac{41}{21} = 10$

$x = 10 - \frac{41}{21}$

$x = \frac{210}{21} - \frac{41}{21} = \frac{210 - 41}{21} = \frac{169}{21}$

$x = 8 \frac{1}{21}$
