((2-3x))/5 <((1-x))/3 <((3+4x))/2

\frac{( 2 - 3 x )}{5} < \frac{( 1 - x )}{3} < \frac{( 3 + 4 x )}{2}

((2x-1))/3 <x+((5-x))/2 <= 3/5+((x+1))/3

\frac{( 2 x - 1 )}{3} < x + \frac{( 5 - x )}{2} \leq \frac{3}{5} + \frac{( x + 1 )}{3}

- 5 < 3 x + 4 < 13

(-101)/3 <5 y/3+3<= 51/3

\frac{- 101}{3} < 5 \frac{y}{3} + 3 \leq \frac{51}{3}
