Question

x+4 2/7-2 1/3=10 помогите срочно надо

Answer 1

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

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

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

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

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

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

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