You can put this solution on YOUR website!
L = age of Louis
\n" ); document.write( "D = age of Dan\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Both are current ages\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"louis is 4 times as old as her son dan\" so \"L+=+4D\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"the sum of their ages is 40\" which means \"L%2BD+=+40\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Plug in \"L+=+4D\" to get...\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"L%2BD+=+40\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"4D%2BD+=+40\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"5D+=+40\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "I'll let you finish up. The goal is to find the value of D. Then use this to find the value of L.\r
