1) F=4x\r
\n" ); document.write( "\n" ); document.write( "2) (F-6)(x-6)=252\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "combining by substitution...\r
\n" ); document.write( "\n" ); document.write( "(4x-6)(x-6)=252\r
\n" ); document.write( "\n" ); document.write( "which has a solution of x=12 (the other is -9/2 and is extraneous for our goal)\r
\n" ); document.write( "\n" ); document.write( "so the father is 48 and the son is 12
\n" ); document.write( "
