Consider the linear system Ax = b (all integer values) with the notation shown below, [1 2 -2 -6 -3 -1 -2 alpha -4 3 9 16 5 7 -6 -15 5 7 -6 -15][x_1 x_2 x_3 x_4] = [1 1 1 1] A^upperarrow x^upperarrow b^upperarrow The element a_24 = alpha has been lost. Assume, however, that before when a was available, the solution with MATLAB was calculated as x = 1.0e+15 * 0.7993 -0.3997 1.1990 -0.3997 Can you determine with this information the missing integer matrix coefficient matrix element a_24 = alpha
