Пошаговое объяснение:

6) 26 – (17 – 2x) = 5x

26 - 17 + 2х = 5х

26 - 17  = 5х - 2х

9 = 3х

х = 9 : 3         х = 3

7) 7х – (3 + 2х) = х + 9

7х - 3 - 2х = х + 9

7х - 2х - х = 9 + 3

4х = 12

х = 12 : 4        х = 3

8) 3x – (10 – 9x) = 22x

3х - 10 + 9х = 22х

3х + 9х - 22х = 10

-10х = 10

х = 10 : (-10)     х = -1

9) 13 – (2x – 5) = x – 3

13 - 2х + 5 = х - 3

-2х - х = -3 - 13 - 5

-3х = -21

х = -21 : (-3)     х = 7

10) 6х – (х + 4) = 16 – 5х

6х - х - 4 = 16 - 5х

6х - х + 5х = 16 + 4

10х = 20

х = 20 : 10       х = 2
