-6 < = 2x + 6 < = 6....subtract 6 from all sections -6 - 6 < = 2x + 6 - 6 < = 6 - 6...simplify -12 < = 2x < = 0...divide all sections by 2 -12/2 < = (2/2)x < = 0/2....simplify -6 < = x < = 0...by the way, I cant put the line under the inequality sign to show the equal sign...so I just put the = sign with the inequality sign
