 frac{3}{9}y+ frac{5}{9}y= frac{36}{5}
 frac{8}{9}y= frac{36}{5}
y=frac{36}{5}* frac{9}{8}
y= frac{81}{20}=4 frac{1}{20}

Не знаю насколько это рационально но, переведем 7 1/5 в неправильную дробь. получаем 1/3y+5/9y=36/5
Общий знаменатель будет 45
Получаем
15y+25y=324
40y=324
y=81/10 у или 8 целых 1/10
И если я не прав то мой мир перевернётся с ног на голову
