What is the solution of 3x + y = 9 and 3x − 5y = 15?

Multiply the first equation by five to yield, 15x + 5y = 45. Add this equation to the second equation from the given,

                                      15x + 5y = 45

                            +         3x - 5y = 15

The answer would be 18x = 60. The value of x is 10/3. Therefore, the answer to this item is letter A.
