The incorrect answer is B.

All you have to do is plug in x to the formulas and see if the are equal.

4x - 2 = 3x + 6

4(8) - 2 = 3(8) + 6

30 = 30

CORRECT


The second is not only not equal, but it is the wrong kind of formula for what you are trying to prove there.

Hope that helps!

Option B is incorrect this is because 3x+6 = 4x - 2 so add 2 to both sides and it becomes 3x+8=4x  there for x is 8
