\n" ); document.write( "The sum of Jocelyn and Joseph's age is 40. \r
\n" ); document.write( "\n" ); document.write( "let joseph's age be x\r
\n" ); document.write( "\n" ); document.write( "and jocelyn's age be y\r
\n" ); document.write( "\n" ); document.write( "x+y=40----------------(1)\r
\n" ); document.write( "\n" ); document.write( "In 5 years, Joseph will be twice as Jocelyn's present age.\r
\n" ); document.write( "\n" ); document.write( "x+5 = 2(y+10)
\n" ); document.write( "x+5 = 2y
\n" ); document.write( "x-2y=-5-----------------(2)
\n" ); document.write( "Solve 1 & 2\r
\n" ); document.write( "\n" ); document.write( "3y=45\r
\n" ); document.write( "\n" ); document.write( "y=15 \r
