ima go with false

Answer 4

If so, it's false.

Answer 5

...??

Why is it false?

Answer 6

Oh no! It's true! I'm sorry, k + 1 = 2k, and 3k - 1 = 2.

Answer 7

2k = 2k

Answer 8

:)

Answer 9

\[ k+1=3k-1 \\ k+1+1=3k-1+1 \\ k+2=3k \\ \ \\ k+2-k = 3k-k \\ 2 = 2k \\ k = 1 \]

Answer 10

@Lily_980 Even if it were 2k = 2k, the equation would still be true.

These are "false equations":

0 = 1
1 = 2
536= 942

--

These are "true equations":

0 = 0
1 = 1
x = x

Both sides are equal.

BTW, I don't think "true/false" is correct terminology.

Answer 11

"Oh no! It's true! I'm sorry, k + 1 = 2k, and 3k - 1 = 2."

she has conceeded she was wrong. As have I by giving her a medal. I dont think we need a lesson on true and false equations. it was a mistake.

Answer 12

@muntoo There couldn't be another possible way to solve the problem other than a "True or False" problem.

Answer 13

@JamesWolf Right, I'm sorry I am trying to teach others stuff so they don't make the same mistake again.
