dashka20081 $\frac{4+y}{2} - \frac{y+2}{7} \ \textless \ y+3;
 \frac{28+7y-2y-4}{14} \ \textless \ y+3; \frac{24+5y}{14}\ \textless \ y+3;$
24+5y<14y+42
-18<9y
y>-2

2) $\frac{4}{1}+ \frac{7y-3}{5} \ \textgreater \ \frac{3y+5-6y}{4}; \frac{20-7y-3}{5} \ \textgreater \ \frac{-3y+5}{4};$
4(16-7y)<5(-3y+5)
64-28y<-15y+5
-13y<-59
y>59\13

3) $\frac{27-15x-8x}{6} \ \textless \ \frac{6x-3x-1}{6}$
6(27-23x)<6(3x-1)
28<26x
28\26<x
14\13<x
1 1\13<x

4) $\frac{30-18-44x}{24} \geq \frac{4-4x+6x}{6}$
6(12-44x) $\geq$ (4+2x)24
72-264x $\geq$ 96+48x
24 $\geq$ 312x
1\13 $\leq$ x
