Am I mistaken, or doesn't #2 under "strategies," which says $$ x/y=k $$, cover the first seven lines of the comment above.

For example, the first one "a*?=b" can be divided by a on both sides to yield "?=b/a" which can then be reversed by the symmetric property of equality to yield "a/b=?."

Then using x and y instead of a and b, and letting the constant be k instead of ? would give us "x/y=k" just as is written above.

If so, this implies that the formulas written in the page actually are more general, because they cover the seven first lines of the comment. So the comment is actually more specific, and the page is more general.
