You can put this solution on YOUR website!

\n" ); document.write( "The path to the solution is easier if you use a single variable....

\n" ); document.write( "x = son's age
\n" ); document.write( "3x-6 = man's age

\n" ); document.write( "The sum of their ages is 58:

\n" ); document.write( " $\"x+%2B+%283x-6%29+=+58\"$
\n" ); document.write( " $\"4x-6+=+58\"$
\n" ); document.write( " $\"4x+=+64\"$
\n" ); document.write( " $\"x+=+16\"$

\n" ); document.write( "The son's age is x=16
\n" ); document.write( "The man's age is 3x-6 = 48-6 = 42

\n" ); document.write( "By the way....

\n" ); document.write( "\"how old is the man?\" okay....
\n" ); document.write( "\"what is the man's age?\" okay....
\n" ); document.write( "\"how old is the man's age?\" not English....

\n" ); document.write( " \n" ); document.write( "
