how do you find X in the equation: (X*Y)=X?
1 Answer | Add Yours
To solve the X*Y = X for X:
X*Y = X
=> X*Y - X = 0
=> X(Y - 1) = 0
This is possible if X = 0 or if Y - 1 = 0
In the former case X = 0, the latter case gives a value for Y, i.e. Y = 1. X can take on any value if Y = 1.
The solution of the equation is X = 0
