50 1/2 = 50.5 
50.5 + -12.3 
When adding a negative number to a positive number, it basically becomes just subtraction so  50.5 + -12.3 means 50.5 - 12.3
50.5 - 12.3 = 38.2

_____________________________________________________
Explanation:
_____________________________________________________
y = 50 ; since vertical angles are congruent.
180 – (50 + 60) = x ;  since all angles in any triangle add up to 180 degrees. 
↔  x = 180 – (50 + 60) = 180 – (110) = 70.
