5x^2+21x-11y=2x-1,y=1

5 x^{2} + 21 x - 11 y = 2 x - 1, y = 1

(x = \frac{- 19 + 561}{10}, x = \frac{- 19 - 561}{10}, y = 1 y = 1)

Solution steps

[5 x^{2} + 21 x - 11 y = 2 x - 1 y = 1]

Plug the solutions

y = 1

into

5 x^{2} + 21 x - 11 y = 2 x - 1

For

5 x^{2} + 21 x - 11 y = 2 x - 1

, subsitute

y

with

1 : x = \frac{- 19 + 561}{10}, x = \frac{- 19 - 561}{10}

Verify solutions by plugging them into the original equations

Therefore, the final solutions for

5 x^{2} + 21 x - 11 y = 2 x - 1, y = 1

are

(x = \frac{- 19 + 561}{10}, x = \frac{- 19 - 561}{10}, y = 1 y = 1)

q (x) = 2, x^{2} + 6 r (x) = - 2

x_{1} = - 5, x^{2} = 3

x - 2 y = 1, x y = 3

x + y = 3, x^{2} + y^{2} = 2

x + y = 6, x + y = 8
