Answer 1

ו9=40-4

ו9=36

×=36:9

×=4

4•9=40-4

Answer 2

It seems like you've provided an equation with some mathematical symbols, but the equation isn't clear. I see the following elements:

1. Х (X) and У (Y), which are variables.
2. An equation with "X • 9 = 40 — 4 28:х=4," but it's not written in a standard mathematical format, and the symbols don't follow typical mathematical notation.

If you could provide a clearer representation of the equation or clarify your question, I would be happy to help you solve it or explain it.
