Question

this is purely for fun.
2y=4y
what is y

Answer 1

y=0

Answer 2

anyone think different?

Answer 3

2*0 = 4*0
0 = 0 True

Answer 4

It took some of the kids in this class 5 minutes and some didnt get it until it was explained. i just wanted to see if the kids in my class are a little stupid or if its really a tough thing to figure out

Answer 5

If the concept of what an equation means is not explained properly it would be hard for anyone.

Answer 6

not true if you have taken a algebra class and all of us have.

Answer 7

you solve for y. theres nothing hard about that. but for some reason no one thinks about zero

Answer 8

If you try to divide by y you get 2 = 4.

Answer 9

fair enough but thats why you have to use common sense and realize that the only way this could be true is if y=0

Answer 10

Algebraically:
2y=4y
2y-2y=4y-2y
0=2y
0/2=2y/2
0=y
This is how I would explain it.

Answer 11

i mean i do see how it could be hard but yes thats what someone did to solve it

Answer 12

The idea of y belongs to {0} is the solution set is hard to explain properly.

Answer 13

It is the value that makes both y=0 and 2y=4y true statements.

Answer 14

thank you haha. well im going to close this question. but i had a very good conversation on this

Answer 15

thanks for asking :-)
