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!
Please leave your comments behind. thanks for reading my scribe.
