Question

решите пожалуйста!!!

Answer 1

$a)1 frac{2}{7} + x = 2 \ x = 2 - 1 frac{2}{7 } \ x = 2 - frac{9}{7} \ x = frac{5}{7} \ b)y +3 frac{2}{5} = 6 frac{3}{5} \ y = 6 frac{3}{5} - 3 frac{2}{5} \ y = 3 frac{1}{5}$
$c)3 frac{3}{10} - x = 2 frac{7}{10} \ x = 3 frac{3}{10} - 2 frac{7}{10} \ x = frac{6}{10} \ x = frac{3}{5} \ d)y - 7 frac{2}{10} = 1 frac{7}{10} \ y = 1 frac{7}{10} + 7 frac{2}{10} \ y = 8 frac{9}{10}$
