First group all like terms together (note that the signs also change): 3x-6x-4x = -2
Next, solve the equation using normal maths:
3x-6x-4x = -2
-3x-4x = -2
-7x = -2
Then you times each side by -1 (it is nessesary as you want the final ans to be positive):
-7x * -1= -2 * -1
7x = 2
Finally, to find x, just use normal division and your final answer would be:
x= 2/7

It's been a LONG time since I've had to do this, so I may be wrong. Here's what I see, though: Leave the |4x-8| alone for the time being. Add 3x to both sides of the = sign. This will give you |4x - 8| = 9x + 2 Maybe then you start messing with the |4x-8| by subtracting that 2 from both sides and subtracting that 4x from both sides: -10 = 5x Divide both sides by 5, and that leaves you with x = -2. Does that look right?

3x-6x + 2=4x
the best way to do this is combine the like terms (the x's)
-3x + 2 = 4x (Subtract 3x-6x)
2 = 7x (Add 3x to 4x, because you must do the opposite operation to both sides of the equation)
divide both sides by 7 and get 2/7 = x

First add 3x - 6x which = -3x, so
-3x + 2 = 4x
then add 3x to both sides
-3x + 3x + 2 = 4x + 3x, which equals:
2 = 7x
then divide both sides by 7:
2/7 = 7x/7, which equals
2/7 = x

3x-6x +2 =4x >>>>>>>>> combine like terms which is "3x-6x"
-3x+2 = 4x >>>>>>>>>>> add "+3x" for both sides because there is "x" in both sides
2 = 7x >>>>>>>>>>>>>> now divide by "7" both sides because you are trying to make the "x" alone
2/7 = x >>>>>>>>>>>>> thats the solution

3x-6x+2=4x
-3x+2=4x
add 3x on both sides:
2=7x
divide 7 on both sides
2/7=x

3x-6x +2 = 4x
-3x +2 = 4x (Use simple equation like + and - to solve the whole qn)
2 = 4x +3x
2 = 7x
x= 2/7
It's straight forward type of Qn

3x-6x+2=4x -->> move 4x and change sign
3x-6x+2-4x=0 -->> sum all x's --have same grade
-7x = -2 -->> x= 2/7

3x-6x+2=4x
First you need to get all like terms together (xs)
Subtract the 4x to the other side
3x-6x+2-4x=0
Then add and/or subtract all the x's
-3x+2-4x=0
-7x+2=0
Now move the 2 to the other side
-7x=-2
Then divide
-7x/-7=-2/-7
Then simplify
x=2/7
You can also write it as x=.286

1. 3x+2=4x+6x (when u move "-" sign to the right it become "+" sign)
2. 2=10x-3x
3. 2=7x
4. 7x=2 ;
5. x=2/7(answers!)
