Answer: 0.72/20; 1.98/20; 17.3/20
0.036 * 10/10 = 0.36/10 * 2/2 = 0.72/20
0.099 * 10/10 = 0.99/10 * 2/2 = 1.98/20
0.865 * 10/10 = 8.65/10 * 2/2 = 17.3/20

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
