Remember algebra?

Miscellaneous Forums/General Discussion/Remember algebra?

OK, let's have one of you bright-eyed college kids remind me how this is done.
X1 = 512 + X * 44 - Y * 44
X1 is a value I know.

solve for X, I get:                      solve for Y, I get:

X1 - 512 = X * 44 - Y * 44              X1 - 512 = X * 44 - Y * 44

X1 - 512                                X1 - 512
-------- = X - Y            <-right?->  -------- = X - Y
   44                                      44

X1 - 512                                -(X1-512)
-------- + Y = X              right?->  --------- + X = Y
   44                                      44
Problem is, although I know the value of X1, I don't know the value of X or Y, since I'm trying to solve for both of them.
As you can see, I need one to solve the other. I can't remember if there's a way to solve them at the same time.
Any help would be appreciated.
