I would like to but I'm terribly busy right now, perhaps come to the math chat room :-)

As I said at the beginning, a variable is not an object, it is a symbol that represents one or more numbers.

Yes, there exists no value of the variable that will make the equation a true statement. That is what the shorthand notation $x\in\text{{}}$ means.

If I have an equation such as x+2=x+1, what does it mean to say that the equation has no solution?

A variable is not an object, it is a symbol that represents one or more numbers. There are no numbers that make the equation a true statement, thus the solution set that the variable belongs to is empty.
