\"x\" -> shimaran's age now
\n" ); document.write( "\"y\" -> shimaran's son's age now\r
\n" ); document.write( "\n" ); document.write( "By \"shimaran is twice as ols as her son\" we have that:\r
\n" ); document.write( "\n" ); document.write( "\"x+=+2y\"\r
\n" ); document.write( "\n" ); document.write( "\"in four years she will be four times as old as her son was 9 years ago\"\r
\n" ); document.write( "\n" ); document.write( "shimaran's age in four years -> x+4
\n" ); document.write( "shimaran's son's age 9 years ago -> y-9\r
\n" ); document.write( "\n" ); document.write( "\"x%2B4+=+4%28y-9%29\"
\n" ); document.write( "\"x%2B4+=+4y-36\"
\n" ); document.write( "\"x-4y+=+-40\"\r
\n" ); document.write( "\n" ); document.write( "As shimaran's age is twice her son's age, 2y is the same as x.\r
\n" ); document.write( "\n" ); document.write( "\"2y-4y+=+-40\"
\n" ); document.write( "\"-2y+=+-40\"
\n" ); document.write( "\"y+=+20\"\r
\n" ); document.write( "\n" ); document.write( "As shimaran's age is twice her son's age, \"x+=+40\". Problem solved!
