Be careful that you do not confuse the solution x = 0 with “no solution”. The solution x = 0 means that the value 0 satisfies the equation, so there is a solution. “No solution” means that there is no value, not even 0, which would satisfy the equation
There is really no way to show that of I know of without drawing it but here is this. I hope this helps and not really exact on position but that is very close.
