On our previous math test there were questions involving adding, subtracting, multiplying, and dividing. The questions were all algebra questions.

I will show you the anwser's I got and then the correct anwser.

Question 5...-n/3=6..Division question

My anwser... 18/3=3
-n=18
n=18
Correct anwser...
-n/3=6
(3)-n/3=6(3)
-n/1=18/1 n= -18

Question 13..-n=25...Multiplicitive question

My anwser... -n=25
-25=25
-n=25
n=25
Correct anwser...
-n=25
(-1)n/-1= 25/-1
n=-25

Question 15..n-3n=18..subtraction question

My anwser...
n-3n=18
3-3 x6=18
n=3

Correct anwser...
-2n/-2=18/-2
n=-9

Question 16...-9+6=n=2n...additoin question

My anwser...
-9+6=n+2n
-9+6=-3+1=-2+1=-1
n=-1

Correct anwser...
-9+6=n+2n
-3/3=3n/3
-1=n

There is my test scribe I hope it was good enough for you people...anyway for the next scribe I choose... Jayzie GOOD LUCK!!!

Hey it's me Jeff and here is my scribe for the upcoming test on algebra :)

n+9=-4










n-6=14













-9+n=17











12n=48

Here are some questions that were on the test that we did on Dec.15/08

1 Question:

6x-(-3x)+2x-9



Question 2 :
