Decide how many solutions the equation has
WebSolutions to Assignment 2 Question 1. [Exercises 2.1, # 12] Which of the following congruences have solutions: (a) x2 1 (mod 3) (b) x2 2 (mod 7) (c) x2 3 (mod 11) Solution: (a) Note that x 0 (mod 3) implies x2 0 (mod 3) x 1 (mod 3) implies x2 1 (mod 3) x 2 (mod 3) implies x2 1 (mod 3) and the congruence x2 1 (mod 3) has a solution if and only if x 1 … Webone solution, or in nitely many solutions. Hence if it has more than one solution, it has in nitely many. (c)How many solutions can a consistent system of linear equations have? Discuss the di erent possibilities. Solution: A system being consistent means it has solutions at all. There are now two possibilities: either there is exactly one ...
