Question 704532: Yeah, I don't understand the addition method. I've been stuck on this question for a while now.
x+y=3
x-y=5
I have to solve for each variable and then have them check out. I've done it multiple different ways and it won't work. Help?
Answer by ankor@dixie-net.com(22740)   (Show Source):
You can put this solution on YOUR website! x + y = 3
x - y = 5
------------adding eliminates y, find x
2x + 0 = 8
x = 8/2
x = 4
:
In the 1st equation, replace x with 4, and find y
x + y = 3
y = 3 - 4
y = -1
:
In the 2nd equation, check the solutions, replace x and y
4 - (-1) = 5
5 + 1 = 5
