Fifteen years ago a man was two-thirds as old as he will be in 12 years.
\n" ); document.write( " How old is he now? It's x
\n" ); document.write( ":
\n" ); document.write( "x - 15 = \"2%2F3\"(x+12)
\n" ); document.write( ":
\n" ); document.write( "Multiply both sides by 3 to get rid of the annoying demominator
\n" ); document.write( "3(x-15) = 3*\"2%2F3\"(x+12)
\n" ); document.write( ":
\n" ); document.write( "3x - 45 = 2(x+12)
\n" ); document.write( ":
\n" ); document.write( "3x - 45 = 2x + 24
\n" ); document.write( ":
\n" ); document.write( "3x - 2x = 24 + 45
\n" ); document.write( ":
\n" ); document.write( "x = 69 yrs now, an old guy like me!

\n" ); document.write( "\"Fifteen years ago a man was two-thirds as old as he will be in 12 years.\"
\n" ); document.write( "69 - 15 = \"2%2F3\"(69 + 12)
