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
