You can put this solution on YOUR website!
Let us call the father's age x. Since the son, is 1/4 of his father's age, we can call the son's age $\"%281%2F4%29x\"$ . Since the difference in their ages is 30 years (that is, father's age - son's age = 30), we can say that $\"x+-+%281%2F4%29x+=+30\"$
\n" ); document.write( "Now just simplify:
\n" ); document.write( " $\"%281%29x+-+%281%2F4%29x+=+30\"$
\n" ); document.write( " $\"%283%2F4%29x+=+30\"$
\n" ); document.write( "x = 40
\n" ); document.write( "Therefore, the father's age is 40 years, and the son's age is $\"%281%2F4%2940+=+10\"$ years. \n" ); document.write( "

\n" );
