The common point of both graphs must be located onn the line y = x (why?) Therefore solve for x: Spoiler: You should come out with (5, 5)

Therefore solve for x: Spoiler: You should come out with (5, 5) i got the answer that does not have solution... it says (5,5) it's wacky and confusing to follow your step sir... is there any other way?
it's wacky and confusing to follow your step sir... is there any other way? why? ... it would help if you were to show how you solved the equation given to you by earboth.
