Hola!

x + 3 = - 4

x + 3 = - 4x = - 4 - 3

x + 3 = - 4x = - 4 - 3x = - 7

verificamos

- 7 + 3 = - 4

x - 5 = - 11

x - 5 = - 11x = - 11 + 5

x - 5 = - 11x = - 11 + 5x = - 6

verificamos

- 6 - 5 = - 11

- 9 + ( x ) = 5

- 9 + ( x ) = 5- 9 + x = 5

- 9 + ( x ) = 5- 9 + x = 5x = 5 + 9

- 9 + ( x ) = 5- 9 + x = 5x = 5 + 9x = 14

verificamos

- 9 + 14 = 5

4 - ( x ) = 12

4 - ( x ) = 12- x = 12 - 4

4 - ( x ) = 12- x = 12 - 4 - x = 8

4 - ( x ) = 12- x = 12 - 4 - x = 8x = -8

verificamos

4 - (-8) = 12

4 + 8 = 12

12 = 12

x + 7 = - 13

x + 7 = - 13x = - 13 - 7

x + 7 = - 13x = - 13 - 7x = - 20

verificamos

- 20 + 7 = - 13

- ( x ) - 2 = 15

- ( x ) - 2 = 15- x - 2 = 15

- ( x ) - 2 = 15- x - 2 = 15- x = 15 + 2

- ( x ) - 2 = 15- x - 2 = 15- x = 15 + 2- x = 17

- ( x ) - 2 = 15- x - 2 = 15- x = 15 + 2- x = 17x = -17

verificamos

- (-17) - 2 = 15

17 - 2 = 15

15 = 15

- 8 - ( x ) = 17

- 8 - ( x ) = 17- x = 17 + 8

- 8 - ( x ) = 17- x = 17 + 8 - x = 25

- 8 - ( x ) = 17- x = 17 + 8 - x = 25x = -25

verificamos

- 8 - ( - 25 ) = 17

- 8 + 25 = 17

17 = 17

- ( x ) + 6 = 20

- ( x ) + 6 = 20- x = 20 - 6

- ( x ) + 6 = 20- x = 20 - 6- x = 14

- ( x ) + 6 = 20- x = 20 - 6- x = 14x = - 14

verificamos

- ( - 14 ) + 6 = 20

14 + 6 = 20

20 = 20

11 + ( x ) = - 19

11 + ( x ) = - 19x = - 19 - 11

11 + ( x ) = - 19x = - 19 - 11x = - 30

verificamos

11 - 30 = -19

- 19 = - 19
