If you mean how to isolate 'x', there's nothin' to it!
Just move 3x to the left side of the equation and subtract from 6x. You should get 3x=12. Can you take it from there?

Subtract 3x from both sides to get.
6x - 3x = 3x - 3x +12
3x = 12
Divide both sides by 3 to isolate x.
x = 4

6x=3x+12.......original equation
6x-3x=12.......minus 3x from both side so the number 12 will be isolate, also put the same term (the number with x) on one side
3x=12.........simple subraction
3x/3=12/3......simple division
x=4.......final answer

6x = 3x + 12
6x - 3x = 12
3x = 12
x = 12 / 3
x = 4
or was that a trick question now?

6x=3x+12
subtract 3x from each side
3x=12
divide both sides by 3
x=4
