Question

How do you prove a point is the solution?

Answer 1

The solution to what?

Substitute its x and y values (or whatever) in to the original equation, I guess.

Answer 2

System of equations I think, that help?

Answer 3

Yes, then do that. Substitute the x and y back in. If it works, then... it's the solution.

You could also graph the equations and the point will be where they intersect.

Answer 4

Thanks! Just was confused.
