Question

3-5.2p=-5.2p+3 is this conditional equation, a contradiction, or an identity. then describe the solution

Answer 1

Are you able to solve for p on your own?

Answer 2

Actually, just gather terms. Simplify the equation as much as you can.

Answer 3

no these are hard to me

Answer 4

Get all of the ps together.

Answer 5

This is easy. It's an identity

Answer 6

Relax, skippy. Let's help her understand why.

Answer 7

lmao

Answer 8

add 5.2p to both sides.
3 = 3

Answer 9

I know you're excited that you know the answer.

Answer 10

Smooth math, I post comments one at a time, let me do what I do, thanks

Answer 11

I really want to understand how this process works I have a final in 5 weeks

Answer 12

Roseanne, when you get something like this, begin by grouping like terms. Do you know what I mean by that?

Answer 13

I apologize, Hero.

Answer 14

Roseanne, I posted what to do above. Just simply add 5.2p to both sides and see what you get.

Answer 15

Do you know what it means to group like terms?

Answer 16

so combine terms means pull 5.2 and 5.2 together would i add them?

Answer 17

yes hero I thought thank you

Answer 18

very much

Answer 19

add 5.2 to both sides of 5.2?

Answer 20

gosh I want to understand this.

Answer 21

Look at the equation 3-5.2p = -5.2- + 3.
On the left side, there is one term with a p in it. On the right side there is one term with a p in it. You want to have all of the p terms on one side of the equation.

Answer 22

I typed it wrong. It is 3-5.2p = -5.2p +3

Answer 23

okay....

Answer 24

So pick one of the p terms and find a way to move it over to the other side.

Answer 25

Understand? What can you do?

Answer 26

ok

Answer 27

add 3 3 on left side and add 5.2 on left side to cancel?

Answer 28

Yes, but since it's an equality, if you add something to one side, you have to add it to the other side too.

Answer 29

im confused smooth

Answer 30

So you have a p term on both sides, and you want p just on one side.
So you decide to get rid of the p term on the left by adding 5.2p.

Answer 31

You have to add 5.2p to both sides, not just 5.2 You don't add 5.2 separately

Answer 32

3 - 5.2p = -5.2p +3
^ ^
These are terms that are multiplied by the variable p. I want just one of them instead of 2.

Answer 33

If I add 5.2p to the left side, it becomes 3 -5.2p + 5.2p = 3, which is what we want.
But this is a balanced equation, so whatever we add to one side, we have to also add to the other.

Answer 34

So we then add 5.2p to the right side also, and we get -5.2p +3 +5.2p = 3

Answer 35

Which gives us the equation 3 = 3. Did you follow that?

Answer 36

to be honest no these are so hard for me

I dont know why

Answer 37

Which part is confusing?

Answer 38

maybe if we were one on one studying the comp thing is difficult

Answer 40

3-5.2p=-5.2p+3
On the RHS move the +3 to the front of -5.2p. The result is:
3-5.2p= 3-5.2p
Looks like an identity to me.
