what would the following system of equations look like in augmented matrix form?

Question

x + y = 5
3x - y = -1

Answer 1

In linear algebra, an augmented matrix is used to represent a system of linear equations. It consists of the coefficients of the variables along with the constants from the right side of the equations aligned in a single matrix.

Given the system of equations:

1. \$x + y = 5\$
2. \$3x - y = -1\$

The coefficients of \$x\$ and \$y\$ from the first equation are 1 and 1, and from the second equation, they are 3 and -1. The constants are 5 and -1. The augmented matrix form for this system would be:

\[
\begin{bmatrix}
1 & 1 & | & 5 \\
3 & -1 & | & -1 \\
\end{bmatrix}
\]

The lines in the augmented matrix separate the coefficients on the left from the constants on the right, similar to how the equal sign separates them in the equations themselves.
