WebChinese Remainder Theorem Example. Find a solution to x 88 (mod 6) x 100 (mod 15) Solution 1: From the rst equation we know we want x 88 = 6k for some integer k, so x is of the form x = 88 + 6k. So from the second equation, we also want 88 + 6k 100 (mod 15), so we want 6k 12 (mod 15). Use the extended Euclidean Algorithm to nd that 15(1)+6( 2) = 3.
