Chapter 4: Q. 197 (page 443)

Write each system of linear equations as an augmented matrix:

Part (a): 2x+4y=-53x-2y=2

Part (b):3x-2y-z=-2-2x+y=55x+4y+z=-1

Short Answer

Expert verified

Part (a): The augmented matrix is 24-53-22.

Part (b): The augmented matrix is 3-2-1-2-2105541-1.

Step by step solution

01

Part (a) Step 1. Given information and write in augmented matrix.
