It is annoying and my teacher doesn't teach me how to do it. Please help me with this one.
What is also annoying is all that strange typing.

I think what you are trying to say is:

A - B = 25
A : B = 3 : 8

let A = 3x and B = 8x
then A - B = 25
3x - 8x = 25
-5x = 25
x = -5

so A = 3x = -15 , and B = 8x = -40
