Which value of x satisfies both 3x + y = 9 and 3x − 5y = 15?
2 answers:
*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.
The answer to the question is A.
