Answer:
<u>Step-by-step explanation:</u>
An Augmented Matrix is where you take the coefficients of x, y, z and the sum (on the right side of the equal sign) and input them into a matrix. The x, y, z coefficients and the sum will be separated by a line.
3x + 4y - 5z = 8 --> coefficients are: 3, 4, -5, and the sum is 8
x + 2z = -3 --> coefficients are: 1, 0, 2, and the sum is -3
4x - 3y = 6 --> coefficients are: 4, -3, 0 and the sum is 6
