Question

For what Value is the fraction 15-x/x+1 undefined?

Answer 1

x = -1

Explanation:

I think you mean (15 - x)/(x + 1).

`(15 - x)/(x + 1)`

If so, then the denominator cannot equal zero.

Set the denominator equal to zero, and find x.

That will be the x value that makes the fraction undefined.

x + 1 = 0

x = -1

Answer: x = -1

Answer 2

15-(-1)/-1+1 ➡ 16/0 a number divided by 0 is undefined.
