Question

Решите уравнение : 8 10/21 - х = 2 2/21 + 3 1/21

Answer 1

$8 frac{10}{21}-x=2 frac{2}{21}+3 frac{1}{21} \ 8 frac{10}{21}-x=5 frac{3}{21} \ x= 8 frac{10}{21}- 5 frac{3}{21} \ x=3 frac{7}{21} \ x=3 frac{1}{3}$

Answer 2

8 10/21-х=2 2/21+3 1/21
х=8 10/21-(2 2/21+3 1/21)
х= 8 10/21-5 3/21
х=3 7/21
х=3 1/3
