-338=7(4+8b)+5b

- 338 = 7 (4 + 8 b) + 5 b

b = - 6

Solution steps

- 338 = 7 (4 + 8 b) + 5 b

Switch sides

7 (4 + 8 b) + 5 b = - 338

Expand

7 (4 + 8 b) : 28 + 56 b

28 + 56 b + 5 b = - 338

Add similar elements:

56 b + 5 b = 61 b

28 + 61 b = - 338

Move

28

to the right side

61 b = - 366

Divide both sides by

61

b = - 6

3 b^{3} - 13 b^{2} + 10 b

7 - (x + 8) - 4 x = 77

\frac{x}{3} = 10

- ∣ x - 2 ∣ = 4

- x < - 8
