Answer

$-10x+104y+9$

Work Step by Step

Using $a(b+c)=ab+ac$ (or the Distributive Property), and combining like terms, the given expression, $ 3-2[5(x-10y)-(3+2y)] ,$ simplifies to \begin{array}{l}\require{cancel} 3-2[5x-50y-3-2y] \\\\= 3-2[5x-52y-3] \\\\= 3-10x+104y+6 \\\\= -10x+104y+(6+3) \\\\= -10x+104y+9 .\end{array}
