Question

solve the open equation
-3<(or equal to)n+6<(or equal to)7
n>(or equal to) -9 and n<(or equal to)1
n<(or equal to)3 and n<(or equal to)7
N>(or equal to)9 and n<(or equal to)7

n<(or equal to) -9 and n<(or equal to)6

Answer 1

Answer 2

-3 <= n + 6 <= 7 --- subtract 6 from ...well...everywhere
-3 - 6 <= n + 6 - 6 <= 7 - 6 --- simplify
-9 <= n <= 1....so n >= -9 and n <= 1

Answer 3

its the 2nd one

Answer 4

or you could have split it into 2 inequalities and solved each one..
-3 <= n + 6 and n + 6 <= 7
