Let
\n" ); document.write( "Present age of Carol = c
\n" ); document.write( "Present age of Amanda = a\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Carol is 25 years older than her cousin amanda.
\n" ); document.write( "c=a+25............(1)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In 18 years
\n" ); document.write( "Carol will be = c+18
\n" ); document.write( "Amanda will be = a+18
\n" ); document.write( "Then
\n" ); document.write( "carol will be twice as old as amanda will be
\n" ); document.write( "c+18=2(a+18)
\n" ); document.write( "c+18=2a+36
\n" ); document.write( "c=2a+36-18
\n" ); document.write( "c=2a+18............(1)\r
\n" ); document.write( "\n" ); document.write( "Put the value of c from (1) to (2)
\n" ); document.write( "a+25=2a+18
\n" ); document.write( "a-2a=18-25
\n" ); document.write( "-a=-7
\n" ); document.write( "Multiply by -1 both sides of the equation
\n" ); document.write( "a=7\r
\n" ); document.write( "\n" ); document.write( "Put the value of a in (1)\r
\n" ); document.write( "\n" ); document.write( "c=a+25
\n" ); document.write( "c=7+25
\n" ); document.write( "c=32\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Present age of Carol = c = 32 years old
\n" ); document.write( "Present age of Amanda = a = 7 years old\r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
\n" );
