Explanation:
3. What does the text mean when it says that teachers have to "exercise a kind of art like seduction, hypnosis"?
The teacher has to use methods that are increasingly exotic and rare in order to hold the attention of his students.
Teachers, like hypnotists, have to train for a long time before they can seduce their respective audiences.
Educating today's students requires using pedagogical methods that are very much like seduction.
Unable to exercise any kind of traditional discipline in the classroom, there is no choice but to try to control his students through personality and charisma.
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
