Since the sum of two numbers, x and y, is 60, we can set up the equation x+y=60. It is also given that x is twice y, so we can represent this as x=2y. Substituting this into the first equation, we get 2y+y=60, which simplifies to 3y=60 and y=20. Plugging this value of y back into the equation x=2y, we get x=40. Therefore, the value of x is 40. Options A, B, and D are incorrect as they do not correspond to the value of x when substituted back into the original equations.
