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.
