Answer

$-2$

Work Step by Step

Distribute 4 to each term in the brackets on the left hand side. $8x-4(3-x)+20=-6x-28$ Distribute $-4$ to the terms in the parentheses. $8x-12+4x+20=-6x-28$ Combine like terms on the left hand side. $12x+8=-6x-28$ Add $6x$ to both sides. $18x+8=-28$ Subtract 8 from both sides. $18x=-36$ Divide both sides by 18. $x=-2$
