Start by distributing through (remember, the middle term is subtraction so the sign inside the parenthesis will change to plus when you distribute through.)
From there, just combine like terms and isolate the variable:
Looks like Dr. Gerard is right: 1/6 is the answer. Kyle was close, but evidently he made an error when subtracting 1 from both sides (0 - 1 = -1, not 1). Without that, his answer would have also been 1/6 instead of -1/6.
Update: I subsituted x for 1/16 and did confirm this to be accurate, as the final equation (3/3 = 1) is an equality.

Start by distributing through (remember, the middle term is subtraction so the sign inside the parenthesis will change to plus when you distribute through.)
From there, just combine like terms and isolate the variable:
2(2x-4) - 3(4x-1) + 2(x+3) = 0
4x-8 - 12x+3 + 2x+6 = 0
-6x +1 =0
-6x = -1
x = 1/6
First, use MDAS - My Dear Aunt Sally - i.e., multiply and divide terms first before adding or subtracting:
2(2x-4)-3(4x-1)+2(x+3)= 0
4x-8-12x+3+2x+6= 0
Combining like terms, the x's and the numbers:
4x -12x +2x -8+3+6 = 0
Adding up the X's and the numbers:
-6x +1 = 0
x= 1/6
Hey there!
Here's the answer.
2(2x-4)-3(4x-1)+2(x+3)=0 --> Write the problem.
4x-8-12x+3+2x+6=0 --> Expand the above equation.
4x-12x+2x-8+3+6=0 --> Group the x terms together and group the constant terms together.
-6x+1=0 --> Simplify the above equation.
-6x=-1 --> Subtract 1 on both sides of the equation.
x=1/6 --> Divide -6 on both sides of the equation.
So the answer is x=1/6.
Hope it helps!

2(2x - 4) - 3(4x - 1) + 2(x + 3) = 1 - 6 x
Therefore, the solution is x = 1/6
1/6
Expand the equation:
4x-8-12x+3+2x+6=0
Add like terms and solve
-6x=8-3-6, or -6= -1, or 6x=1, or x=1/9 ans.
x=17
1/6 or 0.16 recurring is the correct answer.
...............X=17 .........................
