Answer 1

A) is the correct answer.

The first equation becomes 3x-y=-2.
The second becomes 5x+y=6.

Using the coefficients of x and y, and separating the constants results in the first augmented matrix.

Answer 2

3 -1 -2

5 1 6

Explanation:

An augmented system has the coefficients for the variables and then the solution going across

Rewriting the equations to get them in the form

ax + by = c

-3x+y =2

3x-y =-2

5x+y = 6

The matrix is

3 -1 -2
