[R] singular matrix

[Nongluck Klibbua]

Dear R-users,
I try to use "solve" to get the solution of this matrix.But it has error
happen below.
How  I can solve this problem. 
[1] "a"
          [,1]
[1,] 0.8109437
[2,] 5.7569740
[1] "b"
          [,1]      [,2]
[1,] 0.3141293  2.230037
[2,] 2.2300367 15.831264

Error in solve.default(b, a) : system is computationally singular:
reciprocal condition number = 1.37415e-018

Thanks 
Luck
