$\left \{ {{5y + 4 \ \textless \ 13y - 9} \atop {3y + 6 \ \textless \ 9}} \right. \left \{ {{8y \ \textgreater \ 13} \atop {y \ \textless \ 3 - 2}} \right. \left \{ {{y\ \textgreater \ \frac{13}{8}} \atop {y \ \textless \ 1}} \right.$
 y ∈ ∅

$\left \{ {{4(5-d) \geq 50 + 2d} \atop {3d + 29 \geq 4 - 2d}} \right. \left \{ {{6d \leq -30} \atop {5d \geq -25}} \right. \left \{ {{d \leq -5} \atop {d \geq -\frac{25}{5}}} \right.$
d = -5
