If , when solving an equation, the variable drops out and
1. you end up with a true statement, then there will be an infinite number of solutions, and your equation is an identity
e.g. see above
2. you end up with a false statement , then there will be no solution
e.g. 2x +3 = 2x + 5
3 = 5 , which is false
thus , no solution.
