\n" ); document.write( "a=3r\r
\n" ); document.write( "\n" ); document.write( "Anna's and Rain's ages in 4 years are a+4 and r+4. If we use that we get:
\n" ); document.write( "a+4=2(r+4)
\n" ); document.write( "to say \"Four years form now she will be twice as old as Rain\"
\n" ); document.write( "distribute
\n" ); document.write( "a+4=2r+8\r
\n" ); document.write( "\n" ); document.write( "Sub in 3r for a
\n" ); document.write( "3r+4=2r+8\r
\n" ); document.write( "\n" ); document.write( "subtract 2r from both sides
\n" ); document.write( "r+4=8
\n" ); document.write( "r=4
\n" ); document.write( "a=12
