X and Y can be found easily using the following formula: Code: X=Y+X-Y Y=X+Y-X X/Y can be found because they are already known! Another method for finding X/Y is to KNOW Y where X=1, and multiplying it by X Code: e.g 1234 2468 2*4=8 OR Y*X
Yes it is easy to find X and Y because they can be any real number. Simplifying the above equations you get: X = X and Y = Y So Y = 5 and X = 10 works and Y = 10 and X = 5 works. I guess the question is what number doesn't satisfy the equation?
