If that should be (x) minus 3y, not equals,
then y = minus 4.9 and x = 32.9

Sorry. That's rubbish y = plus 2.45 and x = 25.55

You'd better explain it more clearly, with the correct signs.

^ agree those are the correct answers if it should read x-3y = 18.2

If you subtract the second equation from the first you get:
4y = 9.8 and carry on from there
