Verified answer

4 * (1,5х - 1) - 2 * (х + 2) = 3

6х - 4 - 2х - 4 = 3

6х - 2х = 3 + 4 + 4

4х = 11

х = 11/4 = 2  3/4

--------------------------

6х - 4 * (3х - 4) = 2х

6х - 12х + 16 = 2х

6х - 12х - 2х = - 16

- 8х = - 16

х = (- 16) : (- 8)

х - 2

----------------------------

6 * (2,5х - 1) - 2 * (5х + 1) = 2х

15х - 6 - 10х - 2 = 2х

15х - 10х - 2х = 2 + 6

3х = 8

х = 8/3 = 2  2/3

------------------------------

2х - 0,8 * (х - 0,5) = - 3,2

2х - 0,8х + 0,4 = - 3,2

1,2х = - 3,2 - 0,4

1,2х = - 3,6

х = - 3

-------------------------------
