9(-4+2v)+7v=-211

9 (- 4 + 2 v) + 7 v = - 211

v = - 7

Solution steps

9 (- 4 + 2 v) + 7 v = - 211

Expand

9 (- 4 + 2 v) : - 36 + 18 v

- 36 + 18 v + 7 v = - 211

Add similar elements:

18 v + 7 v = 25 v

- 36 + 25 v = - 211

Move

36

to the right side

25 v = - 175

Divide both sides by

25

v = - 7

(x + 2) (x - 1) (x - 3) > 0

180 - 16 x^{2} = 0

\frac{x}{2} + 7 \geq 2

c^{3} - 27

n^{2} - 10 n + 21
