So we'd simplify this like
First we will multiply 3 by 4x and 2 and also open the brackets aswell!
3(4x+2)-6x
=12x + 6 - 6x (And now we will place the like terms together along with their signs)
=12x - 6x + 6 (and now out here we will simply subtract 12x and 6x and so this will give us our answer)
=6x + 6 ANSWER
