what is 3x-12=14?

Ok bob, what happens if we add 12 to both sides? Why can we do this?
After that step, what happens if we divide both sides by 3? Why is that allowable? What value do we get for x then?

how do I do this Solve for x. 3x – 2y = 6 Add 2y to both sides and then divide both sides by 3, to give you just "x' on the left side. so is this how i work it out 3x-2y=6 3x- 2y= 6 -2y 3x=6-2y x= 2 +2y No. Add 2y to both sides.
