Find all solutions xy E Z 2 5 to the simultaneous equations

Find all solutions (x,y) E Z 2 5 to the simultaneous equations All the solutions should be in reduced numbers mod 5.

Solution

2x+3y=1 and x +4y=3

the solution to the set of equations would be

x = -1   and y = 1

now the soluctions need to be reduced according to the eplorer:

|x| = |-1|: = 1

|y| = |1| = 1
