1/f = 1/p + 1/q. Solve for p.
\n" ); document.write( "Multiply everything by the LCD fpq:
\n" ); document.write( " $\"fpq%2Ff=fpq%2Fp%2Bfpq%2Fq\"$ Cancel matching numerators and denominators.
\n" ); document.write( " $\"pq=fq%2Bfp\"$ Get all p's on the same side of the equal sign.
\n" ); document.write( " $\"pq-fp=fq%2Bfp-fp\"$
\n" ); document.write( " $\"pq-fp=fq\"$ Factor out the p.
\n" ); document.write( " $\"p%28q-f%29=fq\"$ Divide both sides by q-f.
\n" ); document.write( " $\"p%28q-f%29%2F%28q-f%29=fq%2F%28q-f%29\"$
\n" ); document.write( " $\"highlight%28p=fq%2F%28q-f%29%29\"$
