From what you'd posted earlier, I think you're trying to solve by substitution
...? I will assume that you mean "X" and "Y" to be "x" and "y" respectively, since otherwise the system is not solveable.
Since the first equation can easily solved for "y=", that's probably the way to go.. . . . .
Then plug this in, in place of "y", in the second equation:. . . . .
Then solve the linear equation
for the value of x, and back-solve then for the value of y.
