How would u solve

Question

2r\r+5 -2(r+5)(r-4)=4(r-4)

I don't kow if I should distribute the negative 2 to (r+5)
What should I do from here?

Answer 1

check you typing, the way it is
it will turn into a cubic equation.

I have a feeling the middle term should be
-2(r+5)/(r-4) and of course the first term should be
2r/(r+5)
