Kelly is nine years older than her sister
\n" ); document.write( "Kelly's age is one more than twice her sisters age.
\n" ); document.write( "whats is kelly's age?
\n" ); document.write( "-------------
\n" ); document.write( "Let her sister's age be \"x\".
\n" ); document.write( "Then Kelly's age is 2x+1.
\n" ); document.write( "-----------
\n" ); document.write( "EQUATION:
\n" ); document.write( "Kelly's age - Sister's age = 9
\n" ); document.write( "2x+1-x = 9
\n" ); document.write( "x+1=9
\n" ); document.write( "x=8 (Sister's age)
\n" ); document.write( "2x+1 = 17 (Kelly's age)
\n" ); document.write( "===========================
