To solve for x, bring together all the terms with x on one side of the equation. So move 2x to the left side.

  `4x` `=`  `2x` `+` `6`

`-2x`    `-2x`


 `2x` `=`    `0`   `+` `6`

  `2x = 6`

Then, isolate x.



Hence, the value of x in `4x=2x+6` is 3.

then you plug it 3 in for x and you get 4*3=(2*3)+6

which equals 12=12

X is the variable. 

you will subtract 2x from both sides getting 4x-2x=6

then you subtract 2x from 4x and get 2x=6

then you divde each side by to and you get x=3
