You can put this solution on YOUR website!
Let Bill be x years old,let Caroline be y years old.
\n" ); document.write( "Now,
\n" ); document.write( "\"Bill is 1 year less than twice as old as his sister Caroline.\"
\n" ); document.write( "

\n" ); document.write( "twice as old as his sister Caroline means (2y)

\n" ); document.write( "Bill is 1 year less than twice as old as his sister means (2y-1)
\n" ); document.write( "

\n" ); document.write( "(2y-1) is Bill's age,which is 'x'
\n" ); document.write( "x=2y-1
\n" ); document.write( "


\n" ); document.write( "\"The total of their ages is 26\"
\n" ); document.write( "that means
\n" ); document.write( "x+y=26
\n" ); document.write( "we know x=2y-1,so put this value in the above equation
\n" ); document.write( "x+y=26
\n" ); document.write( "(2y-1)+y=26
\n" ); document.write( "3y-1=26
\n" ); document.write( "3y=26+1
\n" ); document.write( "3y=27
\n" ); document.write( "y=9
\n" ); document.write( "x=2y-1=2(9)-1=18-1=17
\n" ); document.write( "


\n" ); document.write( "Bill:17 years old,Caroline:9 years old
\n" ); document.write( "
