The German verbs zwingen and erzwingen look very similar (especially in the past tense as gezwungen and erzwungen) and have similar meanings, but there are some fine points in distinguishing their proper usage. Let's take a look first at some examples of zwingen:

Thus, the verb zwingen refers to the person or company etc. that is being forced or compelled to do something.

The verb erzwingen is also usually translated as "to force" or "to compel," as well as "to enforce," but with erzwingen it is not about who is being forced, but what is actually being enforced, be it a situation, arrangement, or law etc.  

Er hat die Entscheidung erzwungen. 
He forced the decision.

Sie erzwingt ein Versprechen.
She is forcing a promise to be made.

An easy way to remember the difference between the two verbs is that zwingen is always about who is being forced or compelled to do something, and erzwingen is always about what is being forced, compelled, or enforced upon somebody:

Die Regierung wurde gezwungen, die neuen Gesetze zu erzwingen.
The government was compelled to enforce the new laws.

The noun die Bilanz sounds similar to the English word "balance" and is often translated thus, in the sense of a "financial balance" or a "balance sheet," as opposed to getting dizzy and losing your balance, which is das Gleichgewicht. You might occasionally run into the phrase Bilanz ziehen, which sounds a bit odd if you were to translate it literally as "pull balance." Its real meaning becomes clearer when we see the phrase used in some different contexts:

BANNER PLACEHOLDER

Fehmarn kann eine erfreuliche Bilanz ziehen: Es kamen zweitausendneun zehn Prozent mehr Gäste.

Fehmarn strikes a happy balance: ten percent more guests came in two thousand nine.

Although I had long assumed—incorrectly—that "to strike a balance" had to do with physical balancing (die Gleichgewicht), in fact the Oxford English Dictionary defines the phrase as meaning "to determine the exact difference, if any, between the two sides of an account," thus using the same sense of "balance" as the German die Bilanz. As with the English phrase, the German phrase too is probably used more often in a metaphorical sense.

The noun die Bilanz without the verb ziehen is also commonly translated thus: 

Neunzehnhundertachtzehn zeigt uns eine Bilanz.

Nineteen hundred eighteen shows us a result.

The least figurative translation of die Bilanz, however, is simply "the balance sheet."
