HELP PLEASE!!
Will Medal :)

Answer 1

What is the best way to classify each equation?

1. 8x+24=2(4x+12)

2.5x+18-x=2(2x+8)

3. 7(3x-2)=20x-13

4. 3x+2(x-10)=5(x-4)

A. identity
B. contradiction
C. neither

Answer 2

@eyust707 help please

Answer 3

If they are identical/equal its an identity

Answer 4

If they are not equal its a contradiction

Answer 5

well yeah I understand that pero I don't know how to like solve them

Answer 6

Is 8x + 24 the same as 2(4x +12) ?

Answer 7

yeah

Answer 8

Bingo! that means its an identity

Answer 9

ok what about the next one?

Answer 10

like how do i find out if its neither

Answer 11

5x+18-x = 2(2x+8)
4x +18 = 4x + 16

Answer 12

is that true?

Answer 13

no so would it be contradiction or neither?

Answer 14

contradiction

Answer 15

neither means it could be true or it couldn't be true depending on what we plug in for x

Answer 16

contradiction means it is never true

Answer 17

7(3x-2)=20x-13

Answer 18

whats that one?

Answer 19

i think is contradiction

Answer 20

I actually thought that at first too but lets be careful
21x - 14 = 20x -13
21x -1 =20x
x-1=0
x=1

Answer 21

if x is 1 its true

Answer 22

otherwise its not

Answer 23

therefore its neither

Answer 24

3x+2(x-10)=5(x-4)
3x +2x-20 = 5x - 4
5x - 20 = 5x - 4
-20 = -4

Answer 25

nope not true

Answer 26

contradiction

Answer 27

ok thank you :)
