Answer:
x = -5, y = -6, z = -3
Step-by-step explanation:
Given the system of three equations:

Write the augmented matrix for the system of equations

Find the reduced row-echelon form of the augmented matrix for the system of equations:

Thus, the system of three equations is

From the last equation:

Substitute it into the second equation:

Substitute y = -6 and z = -3 into the first equation:

Answer: 103
Step-by-step explanation:
8 x 6.5 = 52,
52 + 8 = 60 (pints in total)
there are 2 cups in 1 pint so 60 x 2 = 120
120 - 17 = 103
