Proposition: Complete and Reduced Residue Systems (Revised)

Let $a > 0$ and $b > 0$ be positive integers which are co-prime $a\perp b.$ Then the integer $ax+by$ runs through all values of

• a complete residue system modulo $ab,$ if the integers $x$ (respectively $y$) run through all values of the complete residue systems modulo $a$ (respectively $b,$)
• a reduced residue system modulo $ab,$ if the integers $x$ (respectively $y$) run through all values of the reduced residue systems modulo $a$ (respectively $b.$)
