Answer 1

у+3 7/11=9 3/22
у=9 3/22-3 7/11
у=9 3/22-3 14/22
у=8 25/22-3 14/22
у=5 11/22
у=5 1/2
ответ: у=5 1/2

Answer 2

$y + 3 \frac{7}{11} = 9 \frac{3}{22}$

$y = 9 \frac{3}{22} - 3 \frac{7}{11}$

$y = \frac{201}{22} - \frac{40}{11}$

$y = \frac{201 \times 1 - 40 \times 2}{22}$

$y = \frac{121}{22}$

$y = \frac{11}{2}$

$y = 5 \frac{1}{2}$
