4 - x - 8 = x + 5

No Solution for x \in R

Solution steps

4 - x - 8 = x + 5

Square both sides:

- 16 x - 128 = x^{2} + 10 x + 25

- 16 x - 128 = x^{2} + 10 x + 25

Solve

- 16 x - 128 = x^{2} + 10 x + 25 : x = - 9, x = - 17

x = - 9, x = - 17

Verify Solutions:

x = - 9

False

, x = - 17

False

The solution is

No Solution for x \in R

x^{2} - x - 7 = x + 4

x + 5 = 9

9 - x^{2} = x + 3

3 t + 4 = - 6

x = 6 x
