Answer:
x = 59 / 8
y = 6
z = -13 / 8
Step-by-step explanation:
For this problem, you simply need to set up the augmented matrix for you to enter into the calculator. Once entered into the calculator, you will be given the values for x, y, and z. Here is the augmented matrix:
3x - 4y + 5z = -10
2x - y - 2z = 12
x + y - z = 15
3 -4 5 | -10
2 -1 -2 | 12
1 1 -1 | 15
Input this augmented matrix into the calculator and you will get these values for x, y, and z:
x = 59 / 8
y = 6
z = -13 / 8
Cheers.
