\n" ); document.write( "--------------
\n" ); document.write( "Equation:
\n" ); document.write( "m + f = 40
\n" ); document.write( "m+3 = (1/2)(f+3)
\n" ); document.write( "-------------------------
\n" ); document.write( "Substitute for \"m\" and solve for \"f\"::
\n" ); document.write( "40-f+3 = (1/2)(f+3)
\n" ); document.write( "43-f = (1/2)(f+3)
\n" ); document.write( "86-2f = f+3
\n" ); document.write( "3f = 83
\n" ); document.write( "-----
\n" ); document.write( "f = 27 yrs 8 mts (Flo's age now)
\n" ); document.write( "---
\n" ); document.write( "Solve for \"m\"::
\n" ); document.write( "m + f = 40
\n" ); document.write( "m + 27 2/3 = 40
\n" ); document.write( "Mo = 12 4 mts (Mo's age now)
