Question

Problema 17, vă rog​

Answer 1

Răspuns:

$\frac{1}{ \frac{2}{a + 1} } = \frac{1}{ \frac{3}{b + 2} } = \frac{1}{ \frac{4}{c + 3 } } \\ = \frac{3}{suma} = > = 3sau1$

a+1=2. a=1

b+2=3. b=1

c+3=4. c=1

a+1=2*3=6. a=5

b+2=3*3. b=7

c+3=4*3. c=9

2/6+3/7+4/3=44/21

sunt bune doar (1;1;1)

Answer 2

a+1=2
A=1
B+2=3
B=1
C+3=4
C=1
A+1=2*3=6
A=5
B+2=3*3
B=7
C+3=4*3
C=9
2/6+3/7+4/3=44/21
