Past Tense of Be
“Be” has an unusually irregular past system rather than one interchangeable past form. In ordinary past-indicative clauses, “was” goes with I/he/she/it and “were” goes with you/we/they. The past participle is “been.” Separately, “were” is used in subjunctive constructions such as hypothetical “if I were …,” so that use should not be confused with ordinary subject-number agreement.
The simple past of “be” is “was” or “were,” depending on the subject; the past participle is “been.” In the past indicative, use “was” with I/he/she/it and “were” with you/we/they. “Were” also has a distinct subjunctive use.

Quick tests
Verb-form test
Are you forming an ordinary past-indicative clause with “be”?
If yes: Use “was” with I/he/she/it and “were” with you/we/they.
If no: If you need a past participle, use “been”; if the construction is subjunctive, “were” follows that separate rule.
Caveat: Subject agreement, subjunctive mood, and participle use are separate grammatical decisions; check which construction the sentence actually requires.
Examples
I was at the office before noon.
“Was” agrees with first-person singular “I” in the ordinary past indicative.
They were ready when the doors opened.
“Were” agrees with plural “they” in the ordinary past indicative.
If I were responsible for the schedule, I would move the meeting.
“Were” marks the subjunctive hypothetical construction.
We have been here since morning.
“Been” is the past participle after “have.”
Further guidance
Core difference
Choose “was” or “were” by subject for ordinary past-indicative clauses; use “been” after auxiliaries that require the past participle.
Fast Test
For ordinary past statements, match “was/were” to the subject. For a participle construction, use “been.” For a subjunctive hypothetical, “were” has its own grammatical role.
Usage Boundary
Do not reduce “be” to one past form: person/number controls ordinary was/were agreement, while subjunctive “were” and participial “been” are separate roles.
