10．已知函数f(1−x)=6−f(x+1)f(1-x)=6-f(x+1)f(1−x)=6−f(x+1)，g(x)=3x+1x−1g(x)=\frac{3x+1}{x-1}g(x)=x−13x+1，若函数f(x)f(x)f(x)与g(x)g(x)g(x)的图象有4个交点(x1(x_{1}(x1，y1)y_{1})y1)，(x2(x_{2}(x2，y2)y_{2})y2)，(x3(x_{3}(x3，y3)y_{3})y3)，(x4(x_{4}(x4，y4)y_{4})y4)，则(x1+x2+x3+x4)+(y1+y2+y3+y4)=(x_{1}+x_{2}+x_{3}+x_{4})+(y_{1}+y_{2}+y_{3}+y_{4})=(x1+x2+x3+x4)+(y1+y2+y3+y4)=[ 16 ]．
