Question

The expression x−y equals 0.7 if x and y have certain values. Evaluate the following expressions with the same values of x and y. What is y−x?

Answer 1

-0.7

Explanation:

`x-y=0.7`

You can choose any digits you wish for
`x` and
`y` but the difference must be 0.7. I chose 1.0 and 0.3.

`x=1\\y=0.3\\x-y=0.7\\\\y-x=\\0.3-1=\\-0.7`
