(1) 3 + x + y = 14 can be written as x + y = 11. Second equation is 2x + y = 15. Subtract both equations to get x = 4. Although there is no need to solve for x.
We have 2 distinct equations and 2 variables, can be solved. Hence sufficient.
(2) We can get 3x = 12 or x = 4. Hence sufficient.
Hence Option D

Statement 1: 3+x+y =14 and 2x + y =15 are enough to find the values of x. Hence, Sufficient.
Statement 2 :3x + 2y = 12 + 2y is enough to find the value of x. Hence, Sufficient.
D is the correct answer.
