Solution steps

Remove roots

- 343 x = - 729 x^{3} + 486 x^{2} - 108 x + 8

Solve

- 343 x = - 729 x^{3} + 486 x^{2} - 108 x + 8 : x = 1, x = - \frac{1}{27}, x = - \frac{8}{27}

x = 1, x = - \frac{1}{27}, x = - \frac{8}{27}

Verify Solutions:

x = 1

True

, x = - \frac{1}{27}

True

, x = - \frac{8}{27}

True

The solutions are

x = 1, x = - \frac{1}{27}, x = - \frac{8}{27}

2 + y = 5 + y

c + 2 = 0

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

x^{2} + 19 x - 18 = 4 x + 2

y, x + y = 8
