WebProblems on Chinese Remainder Theorem: Example 1: Find x, if possible, such that 2x ≡ 5 (mod 7), and 3x ≡ 4 (mod 8) Solution: First, we must know that 2 has an inverse modulo 7, namely 4. So we can write the first equivalence as x ≡ 4 · 5 ≡ 6 (mod 7). (Using the Chinese Remainder Theorem) Hence, we have that: x = 6 + 7k for some k ∈ Z.
