Easy Algebra 1 problem!?
It's probably easy for a lot of you out there, I'm just a little stuck. Please give me step-by-step directions on how to solve this! Thanks!
The question says solve for f:
1/f = 1/a + 1/b
Thanks so much!

Comments
1/f = 1/a + 1/b
Multiply both sides by abf
ab = bf + af
divide both sides by a+b
f = ab/(a+b)
