Question

How do you solve `x/(x-9)-4=9/(x-9)`?

Answer 1

No solution

Explanation:

`x/(x-9)-4=9/(x-9)`

`(x-9)/(x-9)-4=0`

If we guess that `x!=9`, the fraction will be simplified:

`1-4=0`

`-3=0` : No solution

By the other way, if take the value 9 for x we will have a 0 in the nominator and has no solution either.
