let x- Daisy's age
\n" ); document.write( "let y- Cecile's age
\n" ); document.write( " x-5 Daisy's age 5 years ago
\n" ); document.write( " y-5 Cecile's age 5 years ago \r
\n" ); document.write( "\n" ); document.write( "(x-5)+(y-5)= 45
\n" ); document.write( "x-5+y-5= 45=5+5
\n" ); document.write( "x+y= 55
\n" ); document.write( "y= -x+55 -- equation 1\r
\n" ); document.write( "\n" ); document.write( "Cecile is now four times as old as Daisy so,
\n" ); document.write( " 4x=y --equation 2\r
\n" ); document.write( "\n" ); document.write( "4x=y: Substitute y from equation 1
\n" ); document.write( "4x= -x+55
\n" ); document.write( "4x+x=55
\n" ); document.write( "5x= 55
\n" ); document.write( "Divide both sides by 5 to eliminate the numerical coefficient
\n" ); document.write( "5x/5= 55/5
\n" ); document.write( "x= 11
\n" ); document.write( "Daisy is 11 years old.\r
\n" ); document.write( "\n" ); document.write( "y=-x+55
\n" ); document.write( "since x is equal to eleven, so
\n" ); document.write( "y= -11+55
\n" ); document.write( "y= 44
\n" ); document.write( "Cecile is 44 years old.
\n" ); document.write( " \n" ); document.write( "
