Pls include the negatives as well

1. Let R = Zx (Z/5Z), the product of the rings Z and Z/5Z. Find all integers n and all elements (a, r) E R such that (a) n(a,x) = (20, [3]). (b) n(a, x) = (5, [0]). In each part, show your solutions in a table indicating the values of n, a, and r for each solution, like this: (a) n a 20 3 Explain how you arrived at your solutions. A method that relies on trial and error will not count. Note: n(a, r) = (na, nx) if n E Z. d image text
