Evaluate x + y when x = –87 and y = 34. (Points : 1) –121 –53 53 121

OpenStudy (ghostgate):

-87 + 34 = -53. Since one of the numbers is a negative then we change the addition to subtraction and act as if it's a normal problem, but we will have to add that negative sign at the end. I hope this helps!
