Question 159651: Please help me solve this problem step by step. I have spent more than 3 hours between 2 days on it. I have come up with several different answers and when I do the check they never work out. (x= 2.14, x=4, x= 1.25)
5[2-(2x-4)] = 2(5-3x)
5[2(-2x+4)] = 2(5-3x)
5(-4x+8) = 10-6x
-20x+40 = 10-6x
-20x+6x+40 = 10-6x+6x
-20x+6x+40 = 10
-14x+40 = 10
-14x+40-40 = 10-40
-14x = -30
x=2.14
I have done it several different ways. If you could help I would greatly appreciate it. Thank you!

You can put this solution on YOUR website! Please help me solve this problem step by step. I have spent more than 3 hours between 2 days on it. I have come up with several different answers and when I do the check they never work out. (x= 2.14, x=4, x= 1.25)
5[2-(2x-4)] = 2(5-3x)
---------------
There's a lot of stuff here, I'll assume this is the problem, and that you want to solve for x. You didn't say.
-------------
5[2-(2x-4)] = 2(5-3x)
5[2-2x +4] = 10 - 6x
5[6 - 2x] = 10 - 6x
30 - 10x = 10 - 6x
20 - 10x = -6x
20 = 4x
x = 5
