(a) record all transaction for the month of July in the General Journal
(b) Prepare the ledger accounts and trial balance as on July 31, 20x8

I have prepared the T- Accounts, what should I do with the first balances that was given to me

If you have Journalised all the details ,
The first Journal entry portrays the opening balances.
Now that you have the T-accounts prepared
Post all the general journals to the T- accounts.
Close each T-account and Prepare a Trial Balance.
It is a fairly lengthy exercise and no-one is going to do it for you.
Do what is required yourself and then submit it here for review.
The proof is the finalisation of the Trial Balance and that it actually balances.

A post-script:-

Make sure you incorporate a CAPTAL ACCOUNT in your opening balances journal
Otherwise your trial balance will not balance.
