Решите уравнение:1)7 7/30-(5 11/30-y)=3 19/30;2)(x-1 9/17)+2 14/17=5 5/17.

Решите задачу:

$7\frac7{30}-\left(5\frac{11}{30}-y\right)=3\frac{19}{30}\\7\frac7{30}-5\frac{11}{30}+y=3\frac{19}{30}\\y=3\frac{19}{30}-7\frac7{30}+5\frac{11}{30}=1\frac{23}{30}\\\\\\\left(x-1\frac9{17}\right)+2\frac{14}{17}=5\frac5{17}\\x-1\frac9{17}+2\frac{14}{17}=5\frac5{17}\\x=5\frac5{17}+1\frac9{17}-2\frac{14}{17}=4$
