identify the property and equation that satisfies the following statement: the solution of an equation is x=-2.
included would be the solution...
Always. Every ordered pair is the solution to infinitely many equations.
not always but most of the time yes
Yes and sometimes it can have more than one solution.
an equation ---------- has a soultion? a)always B)sometimes C)never
Does a multi-step equation sometimes, always, or never have a solution?

Always. Every ordered pair is the solution to infinitely many equations.
An equation can have zero solutions, one solution, two solutions, or many solutions. A solution is any number that, when replaced into the equation, will give an equality. An example of an equation without a solution is x = x + 1. No matter what number you use for "x", the right part will always be one more than the left part. Therefore, the equation has no solution. (Also, if you subtract "x" from each side, you get the equation 0 = 1, which is obviously false.)
No. Sometimes they are both extraneous.

Yes and sometimes it can have more than one solution.
The solution set is the answers that make an equation true. So I would call it the solution.
A linear equation in one variable has one solution. An equation of another kind may have none, one, or more - including infinitely many - solutions.
Solution. A solution of an equation is a number that satisfy the equation. This means that if you replace this number on the equation and check it, the equation will be true. When you solve an equation you can find some roots, but not all of them satisfy the equation. Thus always check your answers after resolving your equation, and eliminate as solution the answers that don't make the equation true or undefined.
