One-third of Ellen's age last year plus double her age next year is 11 years.
\n" ); document.write( " How old is Ellen?
\n" ); document.write( ":
\n" ); document.write( "let e = her present age
\n" ); document.write( ":
\n" ); document.write( "write an equation just like it says.
\n" ); document.write( " $\"1%2F3\"$ (e-1) + 2(e+1) = 11
\n" ); document.write( "Get rid of the fraction mult by 3, resulting in:
\n" ); document.write( "e - 1 + 6(e+1) = 33
\n" ); document.write( "e - 1 + 6e + 6 = 33
\n" ); document.write( "e + 6e + 5 = 33
\n" ); document.write( "7e = 33 - 5
\n" ); document.write( "7e = 28
\n" ); document.write( "e = 28/7
\n" ); document.write( "e = 4 yrs old is Ellen
\n" ); document.write( ":
\n" ); document.write( "YOu can confirm this, replace e with 4 in the original equation \n" ); document.write( "

\n" );
