Question

find x and y if x+y=(7 0 3 5and x -y =(3 0 0 4)
​

Answer 1

Answer:

x = 5019.5 and y = 2015.5

Step-by-step explanation:

7035 - 2015.5 = 5019.5

5019.5 - 2015.5 = 3004

(I just used trial and error until I found the correct solution for y, I originally guessed 2015, and was pretty close but too low, then tried 2016 which was also close but too high so I found the answer for y was 2015.5, in the middle)
