Question

решите пожалуйста!!!

Answer 1

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