F isn't mentioned in your equation.15.5 = (133.7517 + 8.33k) ÷ (5.891 + k)
F=?
Hi Petro. My first step would be to multiply both sides by (5.891+k). Is that what you did?Find k
15.5 = (133.7517 + 8.33k) ÷ (5.891 + k)
Thank you. You are rightIf F,a,b & c are all constants (ie: just numbers) then you could follow this kind of 'procedure':-
F=(a+bk)÷(c+k)⇒F(c+k)=(a+bk)⇒Fc+Fk=a+bk⇒Fk=a+bk−Fc⇒Fk−bk=a−Fc⇒k(F−b)=a−Fc⇒k=F−ba−Fc
Please now show us your attempt to solve for k
I can't (entirely) agree with your answer, @Petro.K=5.92
But I need a full formula
Moved.I'm afraid "Advanced Math" isn't really the right 'place' for this...it would be better placed in "Beginning Algebra".
