erin is 3 times warrens age:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "warren=w
\n" ); document.write( "erin=3w\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "in 4 years she'll be twice the age of warren:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "erin+4=2(warren+4)
\n" ); document.write( "3w+4=2(w+4)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "how old are each of them now?\r
\n" ); document.write( "\n" ); document.write( "dsitribute--
\n" ); document.write( "3w+4=2w+8\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Subtract 2w--
\n" ); document.write( "w+4=8\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Subtract 4--
\n" ); document.write( "w=4\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Therefore,
\n" ); document.write( "**Warren=4
\n" ); document.write( "**Erin=12\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Check: 3w+4=2(w+4) becomes 12+4=2(8) or 16=16. So the ages are right. \n" ); document.write( "

\n" );
