6P + 3A = 72
\n" ); document.write( "A = 4P
\n" ); document.write( "Substitute the known value of A from the second equation into the first.
\n" ); document.write( "6P + 3(4P) = 72
\n" ); document.write( "6P + 12P = 72
\n" ); document.write( "18P = 72
\n" ); document.write( "Divide each side by 18
\n" ); document.write( "P = 4
\n" ); document.write( ".
\n" ); document.write( "If Paul is 4, then Annette is 16.
