Question

Is this right?

Off my teacher's answer key we use to check our answers, not sure where she's getting the 14

Answer 1

Here's what I did:

Combine like terms: -3|6n-8| = -107
Add 3 to both sdies: |6n-8| = -104

What am I doing wrong here?

Answer 2

5 - 8|6n-8| = -107
5 = -107 + 8|6n-8| (add 8|6n-8| to both sides)
5 + 107 = 8|6n-8| (add 107 to both sides)
112 = 8|6n-8|

can you work out the rest?

Answer 3

Yeah, but where did she get

6n-8 = 14

Answer 4

what would you get if you divided both sides by 8 (on my last equation up there)

Answer 5

Ohhh okay. Thanks!
