If the sum of a fathers and sons age is 53, and the son is 25 years younger then the dad how old is the son.
\n" ); document.write( "==================
\n" ); document.write( "Let
\n" ); document.write( "f = age of the father
\n" ); document.write( ".
\n" ); document.write( "If the son is 25 years younger than the father, then an algebraic expression for the son's age is f - 25.
\n" ); document.write( ".
\n" ); document.write( "We know that the father's age and the son's age add up to 53. In algebra, we write that as
\n" ); document.write( "f + (f - 25) = 53
\n" ); document.write( ".
\n" ); document.write( "Now we just solve this equation for f.
\n" ); document.write( "2f - 25 = 53
\n" ); document.write( "2f = 53 + 25
\n" ); document.write( "2f = 78
\n" ); document.write( "f = 78/2
\n" ); document.write( "f = 39
\n" ); document.write( ".
\n" ); document.write( "So the father is 39 years old. Since the son is 25 years younger, the son is 39 - 25 = 14 years old.
\n" ); document.write( ".
\n" ); document.write( "Checking, we see that their ages add up to 53 because 14 + 39 = 53.
\n" ); document.write( "Bingo!
\n" ); document.write( ".
