Bobet is 3 more than 4 times the age of his son.
\n" ); document.write( "b = 4s + 3
\n" ); document.write( " Next year The sum of their ages will be 40.
\n" ); document.write( " b + 1 + s + 1 = 40
\n" ); document.write( " b + s + 2 = 40
\n" ); document.write( " b + s = 38
\n" ); document.write( "replace b with (4s+3) from the 1st statement
\n" ); document.write( "(4s+3) + s = 38
\n" ); document.write( "4s + s = 38 - 3
\n" ); document.write( "5s = 35
\n" ); document.write( "s = 35/5
\n" ); document.write( " s = 7 yrs is the son's age
\n" ); document.write( ":
