-2x^2y=4-x^2,y=9

- 2 x^{2} y = 4 - x^{2}, y = 9

(x = \frac{2}{17} i, x = - \frac{2}{17} i, y = 9 y = 9)

Solution steps

[- 2 x^{2} y = 4 - x^{2} y = 9]

Plug the solutions

y = 9

into

- 2 x^{2} y = 4 - x^{2}

For

- 2 x^{2} y = 4 - x^{2}

, subsitute

y

with

9 : x = \frac{2}{17} i, x = - \frac{2}{17} i

Verify solutions by plugging them into the original equations

Therefore, the final solutions for

- 2 x^{2} y = 4 - x^{2}, y = 9

are

(x = \frac{2}{17} i, x = - \frac{2}{17} i, y = 9 y = 9)

- x - y = - 3, x^{2} - y = - 1

3 x^{2} - 23 x + 40 = 0, 5 y^{2} - 17 y + 1 y = 0

6 x^{2} + y = 1, 412 x^{2} - y = 4

abb = 6 c, c = 10

x + y = 1, 1 x y = 30
