How would I solve the following problems (solutions are provided!) without guessing and checking:
If n is a positive integer and , find n. (n = 3)
If , what is x? (x = 5)
Anyway, for Q1
This equation is actually not solvable using traditional methods, however, you can tell that since the LHS needs to be a multiple of 2, that means must be odd. So you can just substitute odd integers until you get LHS = RHS.
In this case, works.
