Answer 1

Resposta:

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

2x + 4 = 10

2x = 6

x = 6/2 = 3

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

3x - 6 = 9

3x = 15

x = 15/3 = 5

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

4x - 16 = 8

4x = 24

x = 24/4 = 6

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

5x + 10 = -20

5x = -30

x = -30/5 = -6

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

6x + 18 = -12

6x = -30

x = -30/6 = -5

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

7x + 7 = 7

7x = 0

x = 0/7 = 0

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

8x - 16 = -24

8x = -8

x = -8/8 = -1

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

9x + 0 = 9

x = 9/9 = 1

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

10x + 100 = 400

10x = 300

x = 300/10 = 30

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

11x - 55 = 22

11x = 77

x = 77/11 = 7

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

Dúvidas só perguntar.
