We had a math quiz about algebra. We had 10 question and those questions are very easy. I want to share four questions with u, here is my scribe and I also show you how I solve those questions with verify.

My four questions are:

2.
2n - 9 = - 29
2n + 9 = - 29 + 9
2n = -20
2n/2 = - 20/2
n = - 10
2n - 9 = - 29
2(-10) - 9 = - 29
- 20 - 9 = - 29
- 29 = - 29

3.
- 4n + 16= 4
-4n - 16 = 4 - 16
- 4n = -12
-4n /-4 = -12/-4
n = 3
-4n +16 =4
-4(3) + 16 =4
-12 +16 =4
4 =4

5.
n/-5 +17 =-3
n/-5 -17 =-3 -17
n/-5 =-20
(-5)n/-5=-20(-5)
n =100
n/-5 +17 =-3
100/-5 +17=-3
-20 +17 =-3
-3 = -3

6.
12n +25 = -35
12n -25 = -35 -25
n = -60
12n/12 = -60/12
n =-5
12n +25 =-35
12(-5) +25 =-35
-60 +25 = -35
-35 = -35

so, those are the question I want to share with u. Isn't it easy!

Great job! Your scribe was really colourful, but the first question in light green was kinda hard to see, but thats okay. And also, you should of put a "capital letter" after the "period". But great job though!

Good job Azra! Your scribe was good. You should capitalize the title. Your examples were good and I think you should have made a picture of it so it shows up bigger, or make the font big. Good job again!
