Why can't we substitute the value of any variable, taken from 1st equation in 1st equation?

Expert Answer
Dear Student,
If you will do so, then what you will get is 0 = 0, (LHS = RHS) which is always true, and hence justifying the correctness/reality of the basis of an EQUATION, and NOT giving any further outcome, or values of x and y.
