4 [4 - 5x] = 6x + 4
16-20x = 6x + 4
16 -4 = 20x + 6x
12 = 26x
12/26 = x
6/13 = x

I get x = 6/13.
Multiply-out the left side, add 20x to each side, subtract 4 from each side, divide-through by 26. x = 12/26, simplifying to 6/13.

4 [4 - 5x] = 6x + 4
Rearrange to get X on one side of the equation.
4*4 - 5*4*x = 6x + 4
6x - 5*4*x = 4 - 4*4
(6 - 5*4 ) x = 4 - 4*4
x = 4 - 4*4 / (6 - 5*4 )
x = 4 - 16 / ( 6 - 20 )
x = -12 / ( - 14 )
x = 12 /14
x = 2*2*3 / 2* 7
x = 2*3 / 7
z = 6 /7

Just a thought, but I am not getting that X answer, are you sure the info is correct?
I am mean years of college I have written down lots of problems transposing numbers.

4(4-5x)=6x+4
1) Distribute the 4:
16-20x=6x+4
2) Now solve for x:
-26x=-12
x = 6/13
To: The SISU kid
I think the answer might be incorrect.
4(4-5x)= 6x+4
16-20x=6x+4
16-4=6x+20x
12=26x
x=12/26=6/13

4 [4 - 5x] = 6x + 4
16 - 20x = 6x + 4
12 = 26x
12/26 = x
6/13 = x
6/13 does not equal 10/7
The answer supplied to you is wrong, very wrong.

You can get x = 10/7 if you left of a negative sign on the first 4.
-4 [4 - 5x] = 6x + 4
-16 + 20x = 6x + 4
14x = 20
x = 20/14
x = 10/7

Don’t let a democrat solve it, it will end up costing you a trillion dollars to solve it.

Check the original equation.
x=10/7 if -4(4-5x)=6x+4, otherwise x=6/13

6/13 or .4615384615 is correct, or approximately the amount of U.S. citizenship held by Barry Soetoro.

To: The SISU kid
4 [4 - 5x] = 6x + 4
16 - 20x = 6x + 4
16 - 20x - 16 = 6x + 4 - 16
-20x = 6x + 4 - 16
-20x = 6x - 12
-20x - 6x = 6x - 12 - 6x
-26x = -12
-26x/-26 = -12/-26
x = -12/-26
x = -6/13
