Question: don't know how to resolve X and Y in Maple

Hi all,

I have Maple 13, and I am learning how to use it.

To start with it, I was trying to resolve the values of X and Y in the following equations:

(1): X + Y = 60

(2) X = Y -12

and here were what I input into Maple

> X+Y = 60;
                                 X + Y = 60
> X = Y-12;
                                 X = Y - 12
> X =;
Error, invalid =
     Typesetting:-mambiguous(X equals, Typesetting:-merror("invalid ="))

Can anyone tell me how to resolve the values of  X and Y in the above equations using Maple please?
