Sum the values from 2 different queries in 1 query

Hi Experts

I have the 2 queries below, each of which gives me one number.  I want to be able to create a query which uses these 2 queries as subqueries so the 2 values can be summed and I have one total.  Can you help?

SELECT Sum([Pnl by GL - Accounting result].[SumOf7 Total Pnl YTD]) AS GL_ACCOUNTING
FROM [Pnl by GL - Accounting result]
WHERE ((([Pnl by GL - Accounting result].ReportCategory)="HTM" Or ([Pnl by GL - Accounting result].ReportCategory)="Loans&Receivables") AND (([Pnl by GL - Accounting result].AcctArea)="BA_AMADEUS" Or ([Pnl by GL - Accounting result].AcctArea)="BA_TOP_UP" Or ([Pnl by GL - Accounting result].AcctArea)="BA_CDS_HDG" Or ([Pnl by GL - Accounting result].AcctArea)="HENDERSON") AND (([Pnl by GL - Accounting result].AccountCode)=5865000000));

and

SELECT Sum([PnL by GL - Interest].[SumOf11 TotalInterest]) AS GL_INTEREST
FROM [PnL by GL - Interest]
WHERE ((([PnL by GL - Interest].ReportCategory)="Loans&Receivables" Or ([PnL by GL - Interest].ReportCategory)="HTM") AND (([PnL by GL - Interest].AcctArea)="BA_AMADEUS" Or ([PnL by GL - Interest].AcctArea)="BA_TOP_UP" Or ([PnL by GL - Interest].AcctArea)="BA_CDS_HDG" Or ([PnL by GL - Interest].AcctArea)="HENDERSON"));
