1. Consider the linear system Ax = b (all integer values) with the notation shown below, 1 -3 -1 -2 - H 5 7 - 2261x11 X2 -4 3 9 16x3 615 LX4- = A X b The element a24 = a 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 a24 = a?
