Julie is 4 times older than Aaron. In 10 years Julie will be twice as old as Aaron. How old are Julie and Aaron?
\n" ); document.write( "------------------------------------------
\n" ); document.write( "Now DATA:
\n" ); document.write( "Let Aaron be x yrs old.
\n" ); document.write( "Then Julie is 4x yrs old
\n" ); document.write( "-------------------------
\n" ); document.write( "10 years from now DATA:
\n" ); document.write( "Aaron will be x+10 yrs old.
\n" ); document.write( "Julie will be 4x+10 yrs old.
\n" ); document.write( "------------------------------
\n" ); document.write( "EQUATION:
\n" ); document.write( "Julie = twice Aaron's age.
\n" ); document.write( "4x+10 = 2(x+10)
\n" ); document.write( "4x + 10 = 2x + 20
\n" ); document.write( "2x = 10
\n" ); document.write( "x = 5 (Aaron's age NOW)
\n" ); document.write( "4x = 20 (Julie's age NOW)
\n" ); document.write( "=============================
