Question

Which value of x satisfies both 3x + y = 9 and 3x − 5y = 15?

Answer 1

*Hint: In order to find the value of x you could solve this equation by the elimination method and eliminate y.

(3x + y = 9)5
3x - 5y = 15

15x + 5y = 45
3x - 5y = 15

18x = 60
x = 10/3

The answer would be A.

Answer 2

The answer to the question is A.
