Problem Statement

Let a,b,ca,b,c be positive numbers with a+b+c=32\sqrt{a}+\sqrt{b}+\sqrt{c}= \frac{\sqrt{3}}{2} Prove that the system of equations ya+za=1\sqrt{y-a}+\sqrt{z-a}=1 zb+xb=1\sqrt{z-b}+\sqrt{x-b}=1 xc+yc=1\sqrt{x-c}+\sqrt{y-c}=1 has exactly one solution (x,y,z)(x,y,z) in real numbers. It was proposed by Poland. Have fun! :lol:
