2x-2(-4x-24)=-22

2 x - 2 (- 4 x - 24) = - 22

x = - 7

Solution steps

2 x - 2 (- 4 x - 24) = - 22

Expand

- 2 (- 4 x - 24) : 8 x + 48

2 x + 8 x + 48 = - 22

Add similar elements:

2 x + 8 x = 10 x

10 x + 48 = - 22

Move

48

to the right side

10 x = - 70

Divide both sides by

10

x = - 7

4 (x + 3) = 2 (x - 1)

(x - 8) (x + 4) = 0

x^{3} - 3 x^{2} - 13 x + 15 > 0

(- 1)^{4}

(\frac{x}{4})^{3}
