Consider the system of equations x1 +0x2 +5x3 2x4 0x1 + x2 + x3 X1 +0x2 + x3 x1 +3x2 + x3 +4x5 +2x4 +20x5 -2x4 +4x5 -X4 +4x5 = 20 = 10 = 200 = 2 Use MATLAB to answer the following questions. (a) Does the system have one solution, multiple solutions, or no solutions? Justify your answer using results from MATLAB. (b) If there is at least one solution, what is the general solution? If no solution exists, you don't need to answer this question.
