2x+7y=4 −2x−8y =−2 ​

Answer:

-y = 2.

Step-by-step explanation:

2x + 7y= 4

- 2x – 8y = -2  

Adding we eliminate   x because 2x + -2x = 0:-

0 - y = 4  + -2

-y = 2.

A powered by B equals B powered by A. A does not equal B. What's A and what's B?
MrRissso [65]

Answer:

Step-by-step explanation:

I know that there is a zero and a 1 involved in this somewhere. The  only answer I can get which is a bit of a cheat, is

1^0! = 0!^1

These are not exactly the same thing. The trouble is that they are equal. There is a difference between "not the same thing" and "equal."

If I think of something else, I'll put it in a comment.
