[ 7/9 b+9]=2

[\frac{7}{9} b + 9] = 2

b = - 9

Solution steps

[\frac{7}{9} b + 9] = 2

Expand

[\frac{7}{9} b + 9] : \frac{7}{9} b + 9

\frac{7}{9} b + 9 = 2

Multiply both sides by

9

7 b + 81 = 18

Move

81

to the right side

7 b = - 63

Divide both sides by

7

b = - 9

- 3 + 5

- 3 ∣ 9 - 3 x ∣ + 1 = - 5

- 4 a^{2} - a + 4 = 0

\frac{x}{x + 1} \geq 3 x

\frac{x}{x + 1} \geq 3
