Step-by-step explanation:
<u>Step 1: Define</u>
-9x + 1 = -x + 17
<u>Step 2: Solve for </u><em><u>x</u></em>
- Add 9x on both sides: 1 = 8x + 17
- Subtract 17 on both sides: -16 = 8x
- Divide 8 on both sides: -2 = x
- Rewrite: x = -2
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 
so there exists integers k,m such that a = kd and b = md. Then,
. Recall that since k, x, m, y are integers, then (kx+my) is also an integer. This proves that d | t.
