想用VS2008自己编写一个WINDOWS窗体应用程序实现一些计算，不知能不能实现。请大神指导多谢了！
问题类似于求解多元一次方程组：

   Y∈[-0.8,0.8] Z∈[0,1]且是0.2倍数； Y1+Y2+Y3+Y4+Y5∈[-4,0] Z1+Z2+Z3+Z4+Z5=2 a b是已知数
  X1=a1+b1Y1+Z1   
  X2=a2+b2Y2+Z2
  X3=a3+b3Y3+Z3      刚才忘了说还已知X1 X2 X3 X4 X5四舍五入后的整数部分
  X4=a4+b4Y4+Z4
  X5=a5+b5Y5+Z5
  
用C#编程语言可以实现X1 X2 X3 X4 X5的所有可能解吗
如果可以的话大致的步骤劳烦大神解疑再次感谢！

用电脑来解方程是没问题的

不过这个方程俺看不懂  就无法帮你了

5个多元一次方程组呀 大神你的意思是说无法用C#语言达到目的吗？那我应该去C++或者其他方向去考虑解决了？

原来是版主失敬O(∩_∩)O哈哈~
