Answer 1

9 + x = 11

x = 11 - 9

x = 2

COMPROBACIÓN

9 + x = 11

9 + 2 = 11

11 = 11

7 + X = -2

X = -2 - 7

X = -9

COMPROBACIÓN

7 + X = -2

7 + (-9) = -2

7 - 9 = -2

-2 = -2

- 6 + X = - 1

X = -1 + 6

X = 5

COMPROBACIÓN

- 6 + X = - 1

- 6 + 5 = - 1

-1 = -1

8 + X = - 9

X = - 9 - 8

X = - 17

COMPROBACIÓN

8 + X = - 9

8 + (-17) = - 9

8 - 17= - 9

- 9 = - 9
