(OP)
hi
please can someone help me and tell me what i 'm doing wrong, i haven't used mathCAD in ages and i'm trying to solve like 9 unknowns so i have put them in matrice form but now mathcad is being picky...
i have attached my mcad file,
thanks a lot

However, you can also solve for the unknown column vector using matrix math as below:
Matrix given in the form: [A]{x}={b}
The solution to {x} is: {x}=([A]^-1)*{b}
Mathcad can perform matrix inversion pretty easily.

RE: solving
The three 1s on the unknown vector r numbers i actually know (the big matrice is a set of 9 equations that i'm, tring to solve.)
and yes sorry i made a stupid mistake with the number of zeros so yes it is 11.

The matrix A is not square so i can't get the inverse
Is there another way of doing this?
I have tried using transpose but mathcad still wont solve the matrix
Thanks
