How do you know if an equation has no solution or infinite solutions

If an equation has no solution, then it means it can't be solved.

If an equation has infinite solutions, it means that the answers are too large to be defined.

Step-by-step explanation:

An equation has no solution if for instance there is an error in that equation.

An equation has infinite solutions or undefined answers if for instance a number is divided by zero.

If an equation has no solutions, then both sides of the equation will not have any variables such as x or a, etc. Both sides should have the same integer like 0 = 0.

If there are infinite solutions, then both sides would have the same product of an integer and a variable: 6x = 6x.
