    2x + 3 = 2x + 4 - 1

    2x - 2x + 3 = 3

    2x - 2x + 3 - 3 = 3 - 3

    0 = 0

    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.
