The answer would be B. 12
Answer: x1 = 0; x2 = 5/3; x3 = 1/3
x1 + 2x2 - x3 = 3 => 2x1 + 4x2 - 2x3 = 6
2x1 + x2 - 2x3 = 1
=> 4x2 - x2 = 5
⇔ 3x2 = 5
⇔ x2 = 5/3
with x2 = 5/3, we have: x1 - x3 = 3 - 10/3 = -1/3
3x1 - 5x3 = 5 - 4.5/3 = -5/3
=> x1 = 0
x3 = 1/3

Answer:
Hyperbola:

Step-by-step explanation:
the given hyperbola has equation:

This is an equation of a hyperbola centered at the origin.
This hyperbola is translated so its center is now at T(4,3)
