Suppose that a, b \in \mathbb{Z}a,b∈Z, not both 00, and let d=\gcd(a, b)d=gcd(a,b). Bezout's theorem states that dd can be writt

lara [203]

Answer:

Step-by-step explanation:

Recall that we say that d | a if there exists an integer k for which a = dk. So, let d = gcd(a,b) and let x, y be integers. Let t = ax+by.

We know that $d | a, d | b$ so there exists integers k,m such that a = kd and b = md. Then,

$t = ax+by = (kd)x+(md)y = d(kx+my)$ . Recall that since k, x, m, y are integers, then (kx+my) is also an integer. This proves that d | t.
