how would you rearrange ab/c-d/f to solve for a?

Question

how would you do this?

Answer 1

The common denominator would be cf,

so multiply the equation by that to eliminate

the denominators. Then set the equation to =0.

The equation would look like:

fab - dc = 0

      +dc      +dc

--------------------

fab        =      dc

----                ---

 fb                  fb

 

a = dc/fb
