Current ages:\r
\n" ); document.write( "\n" ); document.write( "F = 3 + 3S\r
\n" ); document.write( "\n" ); document.write( "In 3 years time:\r
\n" ); document.write( "\n" ); document.write( "F + 3 = 10 + 2(S+3)\r
\n" ); document.write( "\n" ); document.write( "Solving by substitution:\r
\n" ); document.write( "\n" ); document.write( "3 + 3S + 3 = 10 + 2(S+3)\r
\n" ); document.write( "\n" ); document.write( "6 + 3S = 10 + 2S + 6\r
\n" ); document.write( "\n" ); document.write( "S = 10\r
\n" ); document.write( "\n" ); document.write( "F = 33
