Answer
$x = -14$
Work Step by Step
Use the distributive property to get rid of the parentheses:
$4x + 8 - 2x + 20 = 0$
Group like terms together:
$(4x - 2x) + (8 + 20) = 0$
Add like terms:
$2x + 28 = 0$
Subtract $28$ from each side to isolate the $x$ term:
$2x = -28$
Divide each side by $2$ to solve for $x$:
$x = -14$
