$96x-77$

#### Work Step by Step

Using $a(b+c)=ab+ac$ (or the Distributive Property), and combining like terms, the given expression, $7-4[2(3-2x)-5(4x-3)] ,$ simplifies to \begin{array}{l}\require{cancel} 7-4[6-4x-20x+15] \\\\= 7-4[-24x+21] \\\\= 7+96x-84 \\\\= 96x+(-84+7) \\\\= 96x-77 .\end{array}
