Answer:
(x, y) = (4, 0)
Step-by-step explanation:
It looks like you want to solve ...
Adding the two equations gives ...
2x = 8
x = 4 . . . . divide by 2
Then ...
y = 4 - x = 0
The solution is (x, y) = (4, 0).
_____
If you think about what you're seeing when you read the equations, you realize that adding or subtracting y gives the same result. Hence y=0 and x=4.
9 and 4. 9*4 = 36, 9 + 4 =1 1.
So 90^2+90^2=c^2
8100+8100=c^2
16200=c^2
C= ~127.28
