3x - 4 = 11

3x = 15

x = 5

7x - 5 = 16

7x = 16 + 5

7x = 21

x = 3

x + 12 = 8

x = 8 - 12

x = - 4

15x - 10 = 170

15x = 170 + 10

15x = 180

x = 12

2x + 14 = 16

2x = 16 - 14

2x = 2

x = 1

3x - 5 = 4 + x

3x - x = 4 + 5

2x = 9

x = 9 / 2

11x - 1 = 121

11x = 121 + 1

11x = 122

x = 122 / 11

3x - 2 = 2x

3x - 2x = 2

x = 2

5x + 3 = 2x + 15

5x - 2x = 15 - 3

3x = 12

x = 4

16x - 3 = 102 - 5x

16x + 5x = 102 + 3

21x = 105

x = 5

7 - 3(x - 2) = (7 - x)4 - 4x

7 - 3x + 6 = 28 - 4x - 4x

13 - 3x = 28 - 8x

8x - 3x = 28 - 13

5x = 15

x = 3

3x - (7 - 2x) = 6 - 2(1 - 2x)

3x - 7 + 2x = 6 - 2 + 2x

5x - 7 = 4 + 2x

5x - 2x = 4 + 7

3x = 11

x = 11 / 3

Espero que te ayude = ).
