Question 1116339
.
Let me first help you to formulate your problem.


<pre>
    You want to find the elements p, q, r and s of the matrix  X = {{{(matrix(2,2, p,q, r,s))}}}  from the equation


    {{{(matrix(2,2, p,q, r,s))}}}  - {{{(matrix(2,2, 2, -8, -4, 2))}}} = {{{(matrix(2,2, 4, -6, 2, -8))}}}.


    You have four element-to-element equations


        Cell (1,1)   For "p":   p -   2  = 4   ====>  p = 4 + 2 = 6;

        Cell (1,2)   for "q":   q - (-8) = -6  ====>  q + 8 = -6  ====>  q = -6 - 8 = -14.



    Following the same pattern, complete the solution on your own.


    You should work with co-named cells of the matrix.
