Its A!
proof>I suspect that the 3- in the front of your problem isn't part of the equation, but the number of the problem. If It is included, then you'll end up with a complex solution, which I doubt you are studying. So assume the problem statement is
sqrt(3x-5) = 4
First square both sides.
3x-5 = 16
Solve for x
x = 7

You should find x ? right. Now. First you should add 5 to both sides of the equation
