The fields in question are more important than the values. It looks like your using the right value. if the state select is a single value and the city is a text field and the values you’re using match the values in the DB then I don’t see anything in the meta_query you posted.
I am not too sure about using ‘get_pages()’ though, are you getting “Pages” the default post type when using this function is “page”. If not then you need to specify the post type.
