Evaluate the algebraic expression when $x=4$ and $y=-5$.

$2y-x\(\left\)(3+y\(\right\))$

Evaluate the algebraic expression when $x=-3$ and $y=2$.

$x\(\left\)(20-15y\(\right\))-\(\left\)|2x+y\(\right\)|$

Simplify

$-13+4x+x\(\left\)(9-x\(\right\))$

Simplify

$-3\(\left\)(5-x\(\right\))+10-7x$

Simplify

$3x+14y-7\(\left\)(-x+2y\(\right\))$
