1. Solve the following linear congruence in two variables. Find all incongruent solutions 8r+ 2y 4 mod 10. Hint: rewrite as 8x = 4-2y mod 10 and solve the linear congruence in one variable obtained by successively setting y equal to 0,1,2..... 2. Fifteen pirates steal a sack of gold coins of equal value.
