Let x+3 = Tommy's age in 3 years
\n" ); document.write( " x = Tommy's current age
\n" ); document.write( " x-3 = Tommy's age 3 years ago\r
\n" ); document.write( "\n" ); document.write( "In another 3 years, Tommy will be 3 times as old as he was 3 years ago.
\n" ); document.write( "x+3 = 3(x-3)
\n" ); document.write( "x+3 = 3x-9
\n" ); document.write( " x = 3x-12
\n" ); document.write( " 12 = 2x
\n" ); document.write( " 6 = x\r
\n" ); document.write( "\n" ); document.write( "Check
\n" ); document.write( "6+3 = 3(6-3)
\n" ); document.write( " 9 = 3(3)
\n" ); document.write( " 9 = 9
