Chapter 3.3, Problem 2CVC

Consider the following system:

{ x + y − z = − 1 Equation 1 2 x − 2 y − 5 z = 7 Equation 2 4 x + y − 2 z = 7. Equation 3

We can eliminate x from Equations 1 and 2 by multiplying Equation 1 by _{ࣧࣧࣧࣧࣧ} and adding equations. We can eliminate x from Equations 1 and 3 by multiplying Equation 1 by _{ࣧࣧࣧࣧࣧ} and adding equations.

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.
