Answer:

3  -1  -2

5   1  6

Step-by-step 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

5   1  6

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.
