Question

Use a software program or a graphing utility to solve the system of linear equations. (If there is no solution, enter NO SOLUTION. If the system has an infinite number of solutions, set x5 = t and solve for x1, x2, x3, and x4 in terms of t.) x1 − x2 + 2x3 + 2x4 + 6x5 = 16 3x1 − 2x2 + 4x3 + 4x4 + 12x5 = 33 x2 − x3 − x4 − 3x5 = −9 2x1 − 2x2 + 4x3 + 5x4 + 15x5 = 34 2x1 − 2x2 + 4x3 + 4x4 + 13x5 = 34 (x1, x2, x3, x4, x5) =

Answer 1

1x1 − x2 + 2x3 + 2x4 + 6x5 = 16

3x1 − 2x2 + 4x3 + 4x4 + 12x5 = 33

x2 − x3 − x4 − 3x5 = −9

2x1 − 2x2 + 4x3 + 5x4 + 15x5 = 34

2x1 − 2x2 + 4x3 + 4x4 + 13x5 = 34
