Question

–3 ≤ n + 6 ≤ 7

Answer 1

when you have a left-side and a right-side
you'd add or multiply to both sides to solve for whatever variable

in this case you have, a left-side a middle-side and a right-side
same thing, you'd just have to do it for all 3 sides

–3 ≤ n + 6 ≤ 7
left middle right

Answer 2

thank you jdoe:)

Answer 3

but what would the answer be though?

Answer 4

Well, unless my head is melting... which is quite possible
Let's separate this:
\[
-3 \le n+6 \quad\quad\text{ and } \quad\quad n+6 \le7 \\
-9 \le n \quad\quad\quad \text{ and } \quad\quad n \le 1 \\
-9 \le n \le 1
\]

Answer 5

well... subtract 6 from all sides

Answer 6

n ≤ 3 and n ≤ 7
n ≥ 9 and n ≤ 7
wold be one of those

Answer 7

well... notice pitamar 's lines... same thing, it's just a way to do it piecewise, but the answer is correct

Answer 8

Ironically I liked your way better...

Answer 9

lol thank you both this helped

Answer 10

I don't know which to give the best rsponce too.....

Answer 11

him

Answer 12

\(\bf -3 \le n+6 \le 7\\ \quad \\
\textit{let us subtract 6 from all 3 sides}\\ \quad \\
-3-6 \le n\cancel{+6-6} \le 7-6\implies -9 \le n \le 1\)

Answer 13

ok thank you:) :*
