You can put this solution on YOUR website!
1/f = 1/p + 1/q. Solve for p.
Multiply everything by the LCD fpq:
fpq%2Ff=fpq%2Fp%2Bfpq%2Fq Cancel matching numerators and denominators.
pq=fq%2Bfp Get all p's on the same side of the equal sign.
pq-fp=fq%2Bfp-fp
pq-fp=fq Factor out the p.
p%28q-f%29=fq Divide both sides by q-f.
p%28q-f%29%2F%28q-f%29=fq%2F%28q-f%29
highlight%28p=fq%2F%28q-f%29%29
Happy Calculating!!!!
