Third line - you can't divide both sides by x - x (dividing by zero). Even if done so, although you can divide by x at the fifth line, if the x is zero (the possible solution for the equation at the fifth line), you have to check then if zero is a possible solution. However, you will still find only one solution of infinity.

ReplyDeletex-x = 0 which means the whole thing is 0=0
