1. 7 – 2х = 9 – 3х

2. 11х = 6 + 5(2х – 1)

3. 6(2х – 3) – 3х = 2х – 4

4. 4(3х + 5) – 5(4х – 3) = 3

5. 5х – 3(4х – 1) = 7 – 2(7х + 2)

6. 7х + 10 = 5х + 2

7. 4(3х – 2) + 5 = 9

8. 2х – 5 = 7(3х + 4) + 5

9. 28 – 4(3х + 2) = 5(2х – 7)

10. 3х – 4(5х + 2) – 6(3х – 4) = 1

Answer 1

7 - 2X = 9 - 3X 
2X - 3X = 7 - 9 
- X = - 2 
X = 2 
------------------
11X = 6 + 10X - 5 
11X - 10X = 1 
X = 1 
------------------
12X - 18 - 3X = 2X - 4 
9X - 2X = - 4 + 18 
7X = 14 
X = 2 
------------------
12X + 20 - 20X + 15 = 3 
- 8X = 3 - 35 
- 8X = - 32 
X = 4 
--------------------
5X - 12X + 3 = 7 - 14X - 4 
- 7X + 14X = 3 - 3 
7X = 0 
X = 0

Answer 2

7. x=1; 8. x=-2
