Hi I am trying to solve NC=E to find C. I was thinking I need the inverse of N but before I do that I wanted to check that there is not an easier way to solve for C?

Matrices are:

5x2 matrix

C=

R1(c11,c12)

R2(c21,c22)

R3(c31,c32)

R4(c41,c42)

R5(c51,c52)

5x2 matrix

E=

R1(43,7)

R2(41,4)

R3(29,5)

R4(57,10)

R5(20,6)

5X5 Matrix

N=

R1(1,2,2,3,3)

R2(1,1,3,2,2)

R3(2,1,2,1,2)

R4(1,3,3,2,1)

R5(3,1,1,1,3)
