This should be a fairly simple problem... but for some reason, I'm not understanding it.
Let x_ijkl (for i,j,k,l equal to 1,2) be the unknowns (variables). We have 16 total variables. Let 'a' be a number which will be determined later. Consider the following system of linear equations:
x_1jk1 = ax_11jk for j = 1,2, k = 1,2
x_1jk2 = ax_21jk + x_11jk for j = 1,2, k = 1,2
x_2jk1 = ax_12jk for j=1,2, k = 1,2
x_2jk2 = ax_22jk + x_12jk
a) rewrite the system of equations in matrix form
I guess I'm just confused as to how the subscripts work in this one... I'm assuming that i and j determine the spot in the matrix... so, then, what to k and l represent?
