# Fractional Equation(s) B

**Algebra**Level pending

It is known that there is such a number \(s \) such that if real numbers \(a, b, c, d \) are all neither 0 nor 1, satisfying \(a+b+c+d=s\) and \( \frac{1}{a}+\frac{1}{b}+\frac{1}{c}+\frac{1}{d}=s\), then \( \frac{1}{1-a}+\frac{1}{1-b}+\frac{1}{1-c}+\frac{1}{1-d}=s\). Find \(s \).
