Transcribing to symbols, \"y=kab%2Fc\"
\n" ); document.write( "\"y=k%28ab%2Fc%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Solving for k,
\n" ); document.write( "\"k=yc%2Fab\" and the given values in the first part mean \"k=%2864%2A4%29%2F%2814%2A8%29=8%2A4%2F14=16%2F7\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Your equation then is \"y=%2816%2F7%29%28ab%2Fc%29\".
\n" ); document.write( "Now use the values given in the second part to find y.
