Database.delete() can be used to delete records across multiple objects using Apex in Salesforce.

Sample Code:

List < Id > toDeleteIds = new List < Id > { 
'0WO2M000000mbwnWAA',  
'5002M00000mnEdCQAU',  
'0WO2M000000qewsWAA',  
'a0k2M000066AYgKQAW'
};    
  
Database.DeleteResult[] deleteResults = 
	Database.delete( toDeleteIds, true );  
for ( 
	Database.DeleteResult dr : 
	deleteResults 
) {     
				
	if ( !dr.isSuccess() ) {  

		for ( 
			Database.Error err : 
			dr.getErrors() 
		) {  

			System.debug(
				LoggingLevel.Error, 
				'The following error has occurred.'  
				+ '\n' + err.getStatusCode() + 
				': ' + err.getMessage() +
				'\n fields that affected this error: ' 
				+ err.getFields()
			);  

		}  

	}  

}  

Note:
Don’t include child record ids and master records ids if they are strongly coupled( Master Detail Relationship ).
