+23254 x = 2 - 3y
3x + 9y = 6 ---> 3(2 - 3y) + 9y = 6
6 - 9y + 9y = 6
6 - 0 = 6
6 = 6
There is no single answer; there are an infinite number of values that work.
If you rearranged the first equation to get x + 3y = 2 and then multiply this equation by 3, you would get 3x + 9y = 6 which is exactly the same equation as the second equation. So any combination of numbers for x and y that solve the first equation also solves the second, and there are an infinite number of possible answers.
