#### Answer

The solution is -9

#### Work Step by Step

2(x+5) +8 =0
2x+2$\times$ 5 +8=0 Apply the distributive property
2x +10+8=0 Simplify
2x+18 =0 Subtract 18 from both sides
2x+18-18=0-18
2x=-18 Divide both sides by 2
$\frac{2x}{2}$=$\frac{-18}{2}$
x=-9
The solution is -9
Check
2(x+5) +8 =0 Replace x to -9
2(-9+5) +8 =0 Simplify inside the parentheses
2(-4) +8 =0 multiply
-8+8=0
0=0
