    first use the distributive property \(a(b+c)=ab+ac\)

    Is that really the best course of action? I would think that subtracting 28, and then dividing by -6...etc would be faster.

    this action will lead to dividing by 12 in the end,whicj is simpler than dividing by -6

    Personally, this is my approach: 28-6(2x+4)=124 ---Subtract 28 -6(2x+4)=96 ---multiply by -1, then divide by 6 (2x+4)=-96/6=-16 ---rewrite as 2x+4=-16 ---subtract 4 2x=-20 ---divide by 2 x=-10 This is my way of doing these kinds of questions, but there are definitely others.

    28-6(2x+4)=124 distribute 28 - 12x - 24 = 124 28 - 24 - 124 = 12x -120 = 12x x = -10
