\n" ); document.write( "Father: F
\n" ); document.write( "You can substitute with x and y if required.
\n" ); document.write( ":
\n" ); document.write( "P = 1/5F
\n" ); document.write( "P+F = 48 substitute for P
\n" ); document.write( "1/5F+F = 48
\n" ); document.write( "Multiply both sides times 5:
\n" ); document.write( "F+5F = 240
\n" ); document.write( "6F = 240
\n" ); document.write( "F = 240/6 = 40 The father is 40
\n" ); document.write( "And Peter: 40*1/5 = 40/5 = 8 Peter is 8
