Question

What if the elimination method results in 0=0?

Answer 1

If you end with `0=0`, then it means that the left-hand side and the right-hand side of the equation are equal to each other regardless of the values of the variables involved; therefore, its solution set is all real numbers for each variable.

Answer 2

Assuming you did the elimination right, you are most likely dealing with the same equation, though the other equation is scaled by a factor.
