Let f = father's present age
\n" ); document.write( "let w = wife's age
\n" ); document.write( "let s = son's age
\n" ); document.write( ":
\n" ); document.write( "Write an equation for each statement
\n" ); document.write( ":
\n" ); document.write( "\"Ten yrs ago, the age of father was 33,
\n" ); document.write( "f = 33 + 10
\n" ); document.write( "f = 43
\n" ); document.write( ":
\n" ); document.write( "\" his present age is 5 more than his wife's age;\"
\n" ); document.write( "f = w + 5
\n" ); document.write( ":
\n" ); document.write( "\" their son's age is half of his mother,\"
\n" ); document.write( "s = .5w
\n" ); document.write( ":
\n" ); document.write( "\"the sum of their ages now is 120.\"
\n" ); document.write( "f + w + s = 120
\n" ); document.write( "Replace f with (w+5), replace s with .5w
\n" ); document.write( "(w+5) + w + .5w = 120
\n" ); document.write( "2.5w = 120 - 5
\n" ); document.write( "2.5w = 115
\n" ); document.write( "w = 115/2.5
\n" ); document.write( "w = 46 yrs is the wife's age
\n" ); document.write( "then
\n" ); document.write( ".5(46) = 23 yrs is the son's age
\n" ); document.write( "and
\n" ); document.write( "46 + 5 = 51 yrs is the father's age
\n" ); document.write( ";
