let m = Mom's age
\n" ); document.write( "let r = R's age\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " Reema's mother is four times as old as Reena.
\n" ); document.write( "m = 4r
\n" ); document.write( " after 5 years, her mother will be three times as old as she will be then.
\n" ); document.write( "m + 5 = 3(r+5)
\n" ); document.write( "m + 5 = 3r + 15
\n" ); document.write( "m = 3r + 15 - 5
\n" ); document.write( "m = 3r + 10
\n" ); document.write( "replace m with 4r, from the first statement
\n" ); document.write( "4r = 3r + 10
\n" ); document.write( "4r - 3r = 10
\n" ); document.write( "r = 10 yrs is R's age
\n" ); document.write( "then
\n" ); document.write( "4(10) = 40 yrs is Mom's age
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check this in the 2nd statement
\n" ); document.write( "\"after 5 years, her mother will be three times as old as she will be then?\"
\n" ); document.write( "40 + 5 = 3(10 + 5) \n" ); document.write( "

\n" );
