this question seems easy but i can't get it right.
The sum of two numbers is 752, and their difference is 174. What are the two numbers?
this is what i did:
x+y=752
x-y= 174
from this i got x=454 and y=298
the book says 463 and 298 are the solutions.
is the book wrong cause i can't seem to get the 463?
