please help me with this problem , i need to know what the steps are on how to find x  ----               28-6(2x+4)=124     .

hartnn · Answer

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

hartnn · Answer

and tell me what u get for 6(2x+4)

cathyangs · Answer

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

anonymous · Answer

yeah i dont remember the teacher saying anything about doing that hartnn

hartnn · Answer

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

anonymous · Answer

im confused can somone write out all the steps  , then i can study what you did ? i have other problems like this on my homework i need to know how to solve this type of problem

hartnn · Answer

i mean dividing by -6 and 2 also *

cathyangs · Answer

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

cwrw238 · Answer

either way is same amount of work

anonymous · Answer

acually that way of doing it looks more familiar
