Express the set in tabular method A={x : s sqrt 2=9, 2x=4}

Express the set in tabular method A={x : s sqrt 2=9, 2x=4}
How does your book define "tabular method"? How far have you gotten in applying this definition?

When you reply, please include corrections or clarification of the set in question. For instance, what is meant by "s sqrt"? Since "2x = 4" is true only for x = 2, what is the meaning of the rest of the "definition" of this set?

Please be complete. Thank you! ;)
