f(x)=3,x^4x=-1

f (x) = 3, x^{4} x = - 1

(x = - 1, f = 3)

Solution steps

[f = 3 x^{4} x = - 1]

Solve

x^{4} x = - 1 : x = - 1

For

f = 3

, subsitute

x

with

- 1

f = 3

Verify solutions by plugging them into the original equations

Therefore, the final solution for

f = 3, x^{4} x = - 1

(x = - 1, f = 3)

x + y = 3, x - y = 9

4 x - 2 y = 26, 3 x - 4 y = 17

4 x + 8 y = 20, - 4 x + 2 y = - 30

x + y = 4, x - y = 4

2 x - 5 y = 11, 3 x + 6 y = 3
