Question

Which equation has a solution of n = -1

Answer 1

Choices will be shown below:

Answer 2

n+1=0 is the equation

Answer 3

a. \[\frac{ 1 }{ 2 }n - 6 = -7\]
b. \[-6n + 8 = -2\]
c. \[2(n - 8) = 18\]
d. \[2n + 12 - 3n = 15\]

Answer 4

I picked d, but it wasn't right.

Answer 5

I true to solve all the problems, but it came out that d was right, but unfortunately it wasn't.

Answer 6

are you sure they are asking for -1

Answer 7

Yes, it says, "Which equation has a solution for n = -1"

Answer 8

okay so you solve all of them right what did you get

Answer 9

I got d, and so I submitted the test and it said I was wrong. Right now I am starting to solve them again while you guys see what you come up with.

Answer 10

i think 'c' is relevant to that is lessthan or equal to

Answer 11

I solved a. It equals -0.5.

Answer 12

that is the closet but it still don't equal one unless it is asking for less than or equal to

Answer 13

Yeah, let me solve the rest...

Answer 14

b equals 1.66...7

Answer 15

right

Answer 16

I know what I did wrong! When I was solving c (before now) I solved it right to left, but I didn't remember that I have to do PEMDAS backwards! So c is -18 / 2 = -9 + 8 = -1. Yya!

Answer 17

Thank you both. Im sorry for wasting your times. I need to check my work more often.
