Question

2x-3=2(5+x) is this conditional, contradiction or identity? then describe

Answer 1

dnt knw!

Answer 2

Start by trying to get the two sides of the equal sign to be of the same form.

Answer 3

i.e. distribute the 2 to each of the terms in (5+x)

Answer 4

I have a hard time solving these as it is Im learning though

Answer 5

Stop that

Answer 6

contradiction

Answer 7

I think it is a contradiction.

Answer 8

Yeah, it's a contradiction because -3 doesn't equal 10

Answer 9

I think you all should be a little quieter and actually help her solve the problem.

Answer 10

lol

Answer 11

polpak, it's okay, we're helping her.

Answer 12

Roseanne. Do you understand any of what they said?

Answer 13

so polpak can u help me a lil and show me how to solve these I need to learn

Answer 14

If she has any questions, she can always ask...

Answer 15

It was 2x - 3, not 2x+3

Answer 16

She did ask. And all she got was a pointless one word response that was WRONG the first two times. Perhaps you could start from the position of helping rather than just trying to get the answer out quickly and she might not have to ask the next time.

Answer 17

Hey, I came in late...sorry?

Answer 18

2x - 3 = 10 + 2x [I distributed the 2 on the left side.]
2x = 13 + 2x [I added 3 to both sides.]
0 = 13 [I subtracted 2x from both sides.]
But 0 does not equal 13, this makes it a contradiction.

Answer 19

so there asking to describe the soulution la is what u just mean describing it?

Answer 20

LA-MrC, I question your technique

Answer 21

It's really a one step problem....Just subtract 2x from both sides

Answer 22

ok im confused

Answer 23

Then you have to know what conditional, contradiction, or Identity means

Answer 24

i know what identity means

Answer 25

Roseanne, I have posted a new question for you.

Answer 26

Conditional means only one solution, Contradiction means no solutions, Identity means infinite solutions

Answer 27

condratiction i think means makes no sense like 104 = 5 right? no varaible or am Iwrong

Answer 28

Yes, correct

Answer 29

Conditional doesn't mean only one solution.

Answer 30

It means limited solutions

Answer 31

Not even that.

Answer 32

what does it mean

Answer 33

Contradictory means it is never true (independent of the variables)
Conditional means that is is sometimes true (depends on the values of the variables)
Identity means that it is always true (indepenent of the variables)

Answer 34

ok
