x = - 10 (2)
x = - 20
---------------------------------
x/(-2) = - 10
x = - 10 (- 2)
x = 20
------------------------------------
10 = x/2
2 (10) = x
20 = x
x = 20
------------------------------
- 10 = x/2
2 (- 10) = x
- 20 = x
x = - 20
x: 2 = - 10
x = (- 10)(2)
x = - 20
x : (- 2) = - 10
x = (- 10)(- 2) Multiplicas signos - por - = +
x = 20
10 = x:2
10 * 2 = x
20 = x
x = 20
-10 = x : 2
(- 10)(2) = x
- 20 = x
x = - 20
