Question

If Y=(4x)/x+1 what is Y?

Answer 1

`Y=5`
(but see below)

Explanation:

The question isn't completely clear.

Did you want to solve for `Y` given
`color(white)("XXX")Y=(4x)/x +1`?

Alternatively you might have wanted to solve for `Y` with
`color(white)("XXX")Y=(4x)/(x+1)`

...or, maybe, since this is asked under Differentiation and Quotient Rule, you wanted `(dy)/(dx)`
But, if so did you want it for
`color(white)("XXX")Y=(4x)/x+1` or `Y=(4x)/(x+1)` or something else?

Please clarify, if you are still interested.
