Textbook Question

Chapter 1.1, Problem 6E

Solve each of the following systems.

(a) x 1 − 2 x 2 = 5 3 x 1 + x 2 = 1

(b) 2 x 1 + x 2 = 8 4 x 1 − 3 x 2 = 6

(d) x 1 + 2 x 2 − x 3 = 1 2 x 1 − x 2 + x 3 = 3 − x 1 + 2 x 2 + 3 x 3 = 7

(e) 2 x 1 + x 2 + 3 x 3 = 1 4 x 1 + 3 x 2 + 5 x 3 = 1 6 x 1 + 5 x 2 + 5 x 3 = − 3

(f) 3 x 1 + 2 x 2 + x 3 = 0 − 2 x + x 2 − x 3 = 2 2 x 1 − x 2 + 2 x 3 = − 1

(g) 1 3 x 1 + 2 3 x 2 + 2 x 3 = − 1 x 1 + 2 x 2 + 3 2 x 3 = 3 2 1 2 x 1 + 2 x 2 + 12 5 x 3 = 3 2

(h) x 2 + x 3 + x 4 = 0 3 x 1 + 3 x 3 − 4 x 4 = 7 x 1 + x 2 + x 3 + 2 x 4 = 6 2 x 1 + 3 x 2 + x 3 + 3 x 4 = 6

Solve the linear system of equations attached using Gaussian elimination (not Gauss-Jordan) and back subsitution. Remember that: A matrix is in row echelon form if Any row that consists only of zeros is at the bottom of the matrix. The first non-zero entry in each other row is 1. This entry is called aleading 1. The leading 1 of each row, after the first row, lies to the right of the leading 1 of the previous row.
