forming a formula from a-b=c-d

Postby khazaymeh » Wed Mar 26, 2014 3:03 pm

Hi, I am beginner in mathematics , I have the following relationship:

a-b=c-d

I need to calculate c under the assumption that a, b and d are known values.
I got c=a-b+d
and c=a/b*d

can I use any other formulas?!!

How did you get c=a/(bd)?? Why do you need other formulas? What was the original question they asked you?
