Let \"+x+\" = his body weight at the beginning.
\n" ); document.write( "He lost \"+.0809x+\" of his body weight. That
\n" ); document.write( "means he has \"+%28+1+-+.0809+%29%2Ax+=+.9191x+\" pounds left.
\n" ); document.write( "-----------------------------------------------
\n" ); document.write( "Then he lost \"+1.4+\" pounds
\n" ); document.write( "He has \"+.9191x+-+1.4+\" pounds left
\n" ); document.write( "----------------------------------------
\n" ); document.write( "At this point he has lost \"+.0874x+\" pounds
\n" ); document.write( "That means he has \"+%28+1+-+.0874+%29%2Ax+=+.9126x+\" pounds left
\n" ); document.write( "--------------------------------------------------------
\n" ); document.write( "I can say:
\n" ); document.write( "\"+.9191x+-+1.4+=+.9126x+\"
\n" ); document.write( "\"+.0065x+=+1.4+\"
\n" ); document.write( "\"+x+=+215.385+\"
\n" ); document.write( "He weighed 215.385 pounds at the beginning
\n" ); document.write( "--------------------------------------------
\n" ); document.write( "check:
\n" ); document.write( "He lost \"+.0809%2A215.385+=+17.4246+\"
\n" ); document.write( "---------------
\n" ); document.write( "He lost \"+1.4+\" more
\n" ); document.write( "\"+1.4+%2B+17.4246+=+18.8246+\"
\n" ); document.write( "---------------
\n" ); document.write( "\"+18.8246+=+.0874%2A215.385+\"
\n" ); document.write( "\"+18.8246+=+18.8246+\"
\n" ); document.write( "OK\r
