The number is called a solution.
How did you know that the values of variable raelly satisfy the equation?
You substitute the value of the variable into the equation and simplify. If the rsult is a true statement then that value of the variable really does satisfy the equation.

What is the difference between no solution and undefined?
undefined means you can not do the operation (5/0 is undefined) no solution refers to an equation not having an answer. a solution is a number which you can plug into the variable of an equation and get a true statement. So having no solution means there is no number which you can plug in and get a true statement. As a fraction is not an equation, but an expression it is not right to say that 5/0 has no solution. There is no variable in 5/0, nothing to plug into to get a true or false statement.
Is a number a variable or the product of a number and one or more variables raised to whole number powers?
The statement is true only if either the number is 0, or the variables are all raised to the power 0. In no other case can a variable involved.
What is solving equations about?
It is about finding a value of the variable (or variables) that make the equation a true statement.
What is A value for a variable that makes a statement true?
Such a value is called a "solution" or "root" of an equation.
