1. 7(2х + 3) = 12х + 11 2. 7(-4 + х) + 3х = 4

3. 2(х + 7) – 9 = -2х

4. -3 (5 – х) = 11 + 2х

5.4( х – 1) = 8 – 2х

6. 2х – 3 + 2(х - 1) = 3(х – 3) - 2

7. 9х – 7(-10 - 3х) = -10+(х -7)

1. 7(2х + 3) = 12х + 11 2. 7(-4 + х) + 3х = 4

3. 2(х + 7) – 9 = -2х

4. -3 (5 – х) = 11 + 2х

5.4( х – 1) = 8 – 2х

6. 2х – 3 + 2(х - 1) = 3(х – 3) - 2

7. 9х – 7(-10 - 3х) = -10+(х -7)
