Hola! :3

Resolvemos:

1) x - 2 = 8

x = 8 + 2

x = 10

2) x + 5 = 12

x = 12 - 5

x = 7

3) 3x = 24

x = 24/3

x = 8

4) x/2 = 12

x = 12 × 2

x = 24

5) 2x + 1 = 13

2x = 13 - 1

2x = 12

x = 12/2

x = 6

6) 5x - 4 = 61

5x = 61 + 4

5x = 65

x = 65/5

x = 13

7) 5(x + 1) = 15

x + 1 = 15/5

x + 1 = 3

x = 3 - 1

x = 2

8) 8(x - 1) = 64

x - 1 = 64/8

x - 1 = 8

x = 8 + 1

x = 9

9) x + x + x + x = 48

4x = 48

x = 48/4

x = 12

10) x + 2 + x + 3 = 21

2x + 5 = 21

2x = 21 - 5

2x = 16

x = 16/2

x = 8

Espero haberte ayudado :D
