Ответ:

Пошаговое объяснение:

11/(x+2) = 5

5*(x+2) = 11

5x + 10 = 11

5x = 11 - 10

5x = 1

x = 1 : 5

x = 0,2

============

6/(x+9) = -2/3

-2*(x + 9) =  6*3

-2x - 18 = 18

-2x = 18 + 18

-2x = 36

x = 36 :(-2)

x = -18

=============

(x+2)/(x-4) = 5

x + 2 = 5*(x - 4)

x + 2 = 5x - 20

5x - x = 2 + 20

4x = 22

x = 22 : 4

x = 5,5
