Answer:
2X + 5Y = 300 (1)
X + Y = 120 (2)
DE 1 despejas x
X+Y = 120
X = 120 - Y (3)
Reemplazas en (1)
2X + 5Y = 300
2(120-Y) + 5Y = 300
240 - 2Y + 5Y = 300
3Y = 300- 240
3Y = 60
Y = 60/3
Y = 20
Reemplazas en (3)
X = 120 - Y
X = 120 - 20
X = 100

<span>I believe this is asking you to use an adjective to describe people who are from France. In English: "French". This is how it works in Spanish:
SINGULAR: If it were one person:
- Masculine: *frances* [with accent on *e*]
- Feminine: *francesa*
PLURAL: Two or more people:
- Masculine: *franceses*
- Masculine and feminine together (e.g. a boy and a girl): *franceses*
- Feminine (only girls or women): *francesas*
So, considering Pierre is male and Marie is female, could you guess what your answer should be...? hope this helps</span>
