For this case we must find the values of the expressions given taking into account that the variable "x" is equal to -2. (
)
Expression 1:
![x + 3 =\\-2 + 3 =](/tpl/images/0197/5579/4f09a.png)
Different signs are subtracted and the sign of the major is placed.
![-2 + 3 = 1](/tpl/images/0197/5579/7390c.png)
Expression 2:
![x-1 =\\-2-1](/tpl/images/0197/5579/ccf19.png)
Equal signs are added and the same sign is placed.
![-2-1 = -3](/tpl/images/0197/5579/7e427.png)
