Thank you very much!

Hello! Sorry to bother you again, but I still don't understand this problem.
I have to do the comparison method with these two equations:
1 → 3x  y = 18
2 ⇾ 2y = 6x  120
And when I isolated y, it gave me:
1 → y = 3x + 60
2 → y = 3x  18
But it doesn't work !!! I came to an unrealistic answer. Can you help me isolate my equations, because I think I made a mistake please. It would help me enormously! Thanks in advance!
