it's easy "x" is the # youre looking for so:
1) -31 + (x) = 19
2) (x) = +19 +31
3) (x)= 50
You're # is 50

You need to understand what number is added to the number -19 inn the equation to make 19. Think of it this way, If owed 31 dollars and now you have a surplus of 19 dollars, what would you have? You would have 50 dollars.
This is the same principle for calculating this kind of equation.

as others have said -50. The person who said minus negative 50 is wrong as we all know 2 negatives make a positive. Minus negative 50 - 19 is 31. N'est pas?
