11x + 14 - 7x - 5 = 39 - x

11x - 7x + 14 - 5 = 39 - x

4x + 9 = 39 - x

4x + x = 39 - 9

5x = 30

x = 30/5

x = 6
------------------------------

5 (x + 3) - 11 = 2x + 19

5x + 15 - 11 = 2x + 19

5x + 4 = 2x + 19

5x - 2x = 19 - 4

3x = 15

x = 15/3

x = 5
----------------------------------

4x + 1 + 2 (5 + x) = x + 71

4x + 1 + 10 + 2x = x + 71

6x + 11 = x + 71

6x - x = 71 - 11

5x = 60

x = 60/5

x = 12
