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.

Solve for x<br> -x + 4=22
bekas [8.4K]

Answer: x = −18

Step-by-step explanation:

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-4' to each side of the equation.

4 + -4 + -1x = 22 + -4

Combine like terms: 4 + -4 = 0

0 + -1x = 22 + -4

-1x = 22 + -4

Combine like terms: 22 + -4 = 18

-1x = 18

Divide each side by '-1'.

x = -18

Simplifying

x = -18
