First, we use distributive property to solve the parenthesis.
-X-4-X+7
Now we combine like terms
-2X+3
Thus, your simplified form is -2X+3

[tex]\bf -\cfrac{1}{5}(5x+20)-\cfrac{1}{4}(4x-28)\implies \stackrel{\textit{distributing the factor}}{\cfrac{-1\cdot 5x}{5}+\cfrac{-1\cdot 20}{5}-\cfrac{1\cdot 4x}{4}-\cfrac{1\cdot-28 }{4}}\\\\\\-1x-4-1x+7\implies 3-2x[/tex]
