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.
