Question

What is the definition of no solution?

Answer 1

There is no answer to that problem. There is either a critical error in the problem, or it's just impossible to calculate. For example, x/0 is literally nothing. You can't solve it.

Answer 2

No solution would mean that there is no answer to the equation.

Explanation:

It is impossible for the equation to be true no matter what value we assign to the variable. Infinite solutions would mean that any value for the variable would make the equation true.
