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 $x=0$
