B. No, because it fails the vertical line test.
well from my understanding of the problem and calculations i would say.. (-5.5,0)
3x=4y
x+y=21
x = 21-y
3(21-y)=4y
63-3y=4y
63=7y
y=9
x+y=21
x+9=21
x=12
answer is (12, 9)
K+2/3=-7
K+2=-7x3
K+2=-21
K=-19
The code is 200 because they went under the sea to get the key to work.
