Question 148
Numbers $a$, $b$, $c$ satisfy the conditions:
$$
\frac{a+c}{a+1} = b, \quad \frac{c+b}{c+1} = a, \quad \frac{b+a}{b+1} = c.
$$
What values can the expression $(a+1)(b+1)(c+1)$ take?
$$
\frac{a+c}{a+1} = b, \quad \frac{c+b}{c+1} = a, \quad \frac{b+a}{b+1} = c.
$$
What values can the expression $(a+1)(b+1)(c+1)$ take?
