Question: question with Linsolve

My version is maple 13. I tried to find out how to solve system of linear equations like A*X=b, whre A is a matrix and X and b is a vector, the solution is X:=linsolve(A, b),

But, the system just return the formula of linsolve(A,b) where it replace A and b by their forms of matrix. Simplely , the software doesn't show the result. I tried also evalm(linsolve(A,b)) , but it just return dezens of linsolve(a,b).
