Question: How to: Jacobian and MatrixInverse

I executed a Jacobian function as follows X:=Jacobian([a,b,c,d,e],[y[1],y[2],y[3],y[4],y[5]])
a,b,c,d,e are initialized expressions/equations and
y[i], i=1..5 are the variables and I got the result below

and I'd like to perform an inverse on the result that is X. My objective here is to implement the inverse method(X^(-1)*X) to obtain the variables y[i], i=1..5 but my inverse gives the message

Length of output exceeds limit of 1000000 (I used X^(-1) and MatrixInverse(X))

Pls. someone should tell me what I'm doing wrong and also, if there is another way of doing this.

Please Wait...
