Ok. give your brain a rest and let's see what can be done with this:
\n" ); document.write( "Solve:
\n" ); document.write( "\"1%2Fa+%2B+2%2Fb+=+3%2Fc\" for b. First, subtract \"1%2Fa\" from both sides.
\n" ); document.write( "\"2%2Fb+=+3%2Fc+-+1%2Fa\" Now combine the two fractions on right side.
\n" ); document.write( "\"2%2Fb+=+%283a-c%29%2Fac\" Next, multiply both sides by ac
\n" ); document.write( "\"2ac%2Fb+=+3a-c\" Then multiply both sides by b
\n" ); document.write( "\"2ac+=+b%283a-c%29\" Finally, divide both sides by (3a-c)
\n" ); document.write( "\"2ac%2F%283a-c%29+=+b\"\r
\n" ); document.write( "\n" ); document.write( "So, \"b+=+2ac%2F%283a-c%29\"
\n" ); document.write( "
\n" );
