SOLUTION: Solve for A: 1/A + 1/B + 1/C = D I tried getting A by itself by using common denominators...but no luck (not sure what category this fits in...sorry about that) Thanks in adva

subtracting 1/B and 1/C __ 1/A=D-1/B-1/C

BC is the common denominator __ 1/A=(DBC-C-B)/(BC)

taking the inverse __ A=(BC)/(DBC-C-B)
