A and x1 are 300*1 vectors, x2 is a 1*2000 vector, B is a 300*2000 sparse matrix.
(A-x1)*x2=B
we know A, B, then how can we calculate both vector x1 and x2?

Choose x1_i (1<=i<=300) arbitrarily and x2_j = b_ij/(a_i-x1_i) (1<=j<=2000).

As I already posted, there are infinitly many solutions for x1 and x2 that satisfy your above equations.
If you prescribe x1, then x2 is uniquely determined.
