Solve.
x^2+y^2=9
2z^2-y^2=6

1x² + 1y² = 9
2x² -  1y² = 6
         3x² = 15
          3        3
           x² = 5
           x ≈ 2.236
2(2.236)² - 1y² = 6
2(5) - 1y² = 6
10 - 1y² = 6
-10        -10
     -1y² = -4
       -1     -1
        y² = 4
         y = 2
   (x, y) = (2.236,2)
(x², y²) = (5, 4)
x² + y² = 9

Ai just took the test

Geometric pattern of 2 i’m guessing. not really sure about what you’re asking but i hope this !
