Question

Could you please confirm the following?


They want me to complete the two-column proof.

Given: 11x - 6y = -1; x = 8
Prove: 89/6 = y

After the Given they state the steps. They want me to state what property each step is.

88 - 6y = -1 This is Substitution I think.
-6y = -89 I'm not sure about this one.
y = 89/6 Division Property
89/6 = y Symmetric

Am I correct?
Could you explain to me what property -6 = -89 is?

Answer 1

Yes you are close!

Answer 2

Could you explain to me what property -6 = -89 is? I'm confused on that one.

Answer 3

Did I get one of the other parts wrong as well?

Answer 4

so they give you x, and want you to find y?

Answer 5

No, they want me to name each step made to find the proven with a property.

Answer 6

how did you get -6=89?

Answer 7

It was stated in the problem. It's a -89 by the way. They give me the steps, and they are all correct. They just want me to figure out what property each one is an example of.

Answer 8

Or demonstrates

Answer 9

@Fang02 I think you just have a typo in that 2nd step...

Answer 10

you had:
-6 = -89

I think it should have been -6y = -89

you get this by "moving the 1" from the left side of the equation to the right.

Answer 11

But I'm unsure of the property...

Answer 12

Oh yes, you are correct.

Answer 13

Do you think that I am correct on the other properties?

Answer 14

I think there's another typo in line 3... should be y = 89/6 but I think you correct about it being division property. I think your reasons for the first step (substitution) and last step (symmetric) are both correct.

Answer 15

Do you have properties like "Subtraction" that would describe line 2? I can't recall the list of possible reasons you might use.

Answer 16

Yes, it's a typo. I'll fix that. Yes, subtraction is a choice.

Answer 17

Addition, Subtraction, Multiplication, Division, Symmetric, Reflexive, Transitive, Substitution, and Distributive are the nine properties.

Answer 18

I think that -6y = -89 has the subtraction property, like you suggested. It's the only choice with that response that has all of the other properties in the order that I stated in the original problem.

Answer 19

Thank you!

Answer 20

Would you mind confirming another question real quick Jake?

Answer 21

@Fang02 Sorry, I stepped away but left this question open.... still need help?
