Here is your equation:
To leave the variable 6x by itself, you need to remove everything with it. With the variable is +2. To remove it, you have to do the opposite, which is -2. Subtract 2 from both sides.
The variable is now 6x. You need to find x alone. To do that, divide both sides by 6.
That means your answer is B. x = 2 or C. because the choices are the same.
