Answer :
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
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
