Can you solve with Mathcad this system of equations?

A good sample of cash payments can be found in the "Bourgeois Gentilhomme” by Moliere (http://en.wikipedia.org/wiki/Le_Bourgeois_gentilhomme).

DORANTE: Do you remember well all the money you have lent me?

MONSIEUR JOURDAIN: I believe so. I made a little note of it. Here it is. Once you were given two hundred louis d'or.

DORANTE: That's true.

MONSIEUR JOURDAIN: Another time, six-score.

DORANTE: Yes.

MONSIEUR JOURDAIN: And another time, a hundred and forty.

DORANTE: You're right.

MONSIEUR JOURDAIN: These three items make four hundred and sixty louis d'or, which comes to five thousand sixty livres

DORANTE: The account is quite right. Five thousand sixty livres.

MONSIEUR JOURDAIN: One thousand eight hundred thirty-two livres to your plume-maker.

DORANTE: Exactly.

MONSIEUR JOURDAIN: Two thousand seven hundred eighty livres to your tailor.

DORANTE: It's true.

MONSIEUR JOURDAIN: Four thousand three hundred seventy-nine livres twelve sols eight deniers to your tradesman.

DORANTE: Quite right. Twelve sols eight deniers. The account is exact.

MONSIEUR JOURDAIN: And one thousand seven hundred forty-eight livres seven sols four deniers to your saddler.

DORANTE: All that is true. What does that come to?

MONSIEUR JOURDAIN: Sum total, fifteen thousand eight hundred livres.

DORANTE: The sum total is exact: fifteen thousand eight hundred livres. To which add two hundred pistoles that you are going to give me, which will make exactly eighteen thousand francs, which I shall pay you at the first opportunity.

What is it six-score? (in Russian translation I see 120 louis d'or).

What is relation between louis d'or, livres, sols, deniers, pistoles and francs?
