Answer
$x=0$
Work Step by Step
$-2(x+5)-2=-8-4\rightarrow$ apply distributive property
$-2x-10-2=-8-4\rightarrow$ combine like terms
$-2x-12=-12\rightarrow$ add 12 to both sides
$-2x-12+12=-12+12\rightarrow$ simplify
$-2x=0\rightarrow$ divide both sides by -2
$-2x\div-2=0\div-2\rightarrow$ simplify
$x=0$
