To solve the equation 2x - 6 = 14, first
a) add 6 to both sides. b) add 2x to both sides.
c) subtract 6 from both sides. d) subtract 2x from both sides.

You would add 6, so you can divide both sides by 2 later on in the equation. Since it is subtracting six on one side of the equation you need to add on the other side to cancel it out.
