C. (8,32) because when graphed (8,32) lands on the same line as the others.
Let's form the difference of the two expressions and see what we can learn.
(2y -x) -(2x -y) = 2y -x -2x +y = 3y -3x = 3(y -x)
Since y > x, this is positive, so 2y -x is greater than 2x -y.
(4 + x) / 2 = 42
(2) (2)
4 + x = 84
-4 -4
x = 80
Mike started with 80 cards
Hope I helped :)
if you multiply each x by -5 you will get each y
hope this helps and can i get a Brainliest because in don't have any
