Witryna21 mar 2024 · x is divisible by 3 and not by 2. So x is odd multiple of 3. so, lets get down to choices to check which one is an integer and which is not. (A) x+1 is even and hence (x+1)/2 = I. (B) x/7 may be an integer or may be not. We can't say anything based on the data available with us. (C) x^2 must be a multiple of 3. Witryna15 paź 2024 · QED. (and if all you wanted to prove was that $3 \mid k \iff 3 \mid s$, then literally just replace all the $9$ s with $3$ s). Note that I didn't need to use any quantifiers (symbols like $\forall$ or $\exists$) at all! Quantifiers are great, but don't overuse them. Writing things in words is almost always a good idea.
