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.
