Why is wolfram showing the wrong result? Is there a way to see a step by step solution? If yes, could anyone with wolfram pro check the inverse of f(x)=3+((x)/(2x-3))? Thanks.

Also i know it's the same result but multiplied by -1, but it's wrong!

>> No.8773994

>>8773984
it's not multiplied by -1, it's literally the same. x/y = (-x)/(-y)

Why do you think it's wrong?

It isn't equal:

(3(x-3))/(2x-7) != (3(-x+3))/(-2x+7)

They are equal.

What? Tell me one value for x for which they are not the same.

[math]\frac{-3x+9}{-2x+7} = \frac{(-1)(3x-9)}{(-1)(2x-7)} = \frac{3x-9}{2x-7} = \frac{3(x-3)}{2x-7}[/math]

[math]\frac{-1}{-1} = 1[/math]
