I need a SQL query to combine 2 tables into 1 query result but still having separate rows from each table.

WITHOUT using INSERT or modifying either of the tables

First Table:

2nd Table:

Desired query results:

As you can see, the quantity columns are combined into 1 and all the rows from each table are still separately listed. Please provide me the SQL query to accomplish this. Again, NOT using INSERT or modifying either of the tables. NOT creating a new table either.
