Answer:
Since the sum is 38, y must be 15. And indeed the difference between 23 and 15 is 8, so it's correct.
Answer:
15 & 23
Step-by-step explanation:
I used an insert and check kind of method. Basically you insert numbers and check if they work for both equations. the equations are as follow:
X + Y = 38
X - Y = 8
I inserted various combinations of numbers and we'll use one as reference.
I used 16 and 22. 16 and 22 correctly fits the requirements of the first equation but when we do 22 - 16 we see that it equals 6. this is 2 off from the second equation. Using this info I ask myself, was the answer close or far from the answer needed.
Hope this answered any questions. please comment on this if you need any othern have a nice day!
