1. Simple Algebra Question

Hello Folks,

I am in need to figure this formula out. I will put it in the simplest terms:

Original Formula as noted:
y = (a * b/c * d) - e * f

If I were to enter it in to the computer as this:

y = ((a * b)/(c * d)) - (e * f)

it gives me different results.

1. Could you please advice me on how to separate the original formula with parenthesis?

2. Considering I have all the value's except f, how would I solve for f?

Of course it does, as these are different equations.

Which one is yours? What are the values for $\displaystyle y,b,a,c,e,d$ ?

3. First one is the original. Let me PM you how exactly it was noted in the book...If you don't mind

It is preffered you post it in this thread.

5. Oh ok.

Lets say I have this:
y = (15*5.14/42*120) - .015*X

1. How would you further sperate this with parenthesis?

2. How you I solve for X when y is known?

Thanks again.

y = (15*5.14/42*120) - .015*X

y - (15*5.14/42*120) = - .015*X

(y - (15*5.14/42*120))/(- .015) = X

7. Oh thank you!
