Answer

-5 < x < 6

x < 2 or x > -9

no solution

Answer 1

-9 < x < 2, because -9+2=7 and 2+2=4

you have to us BEDMAS - brackets, exponents, division, multiplication, additition, subtraction

Answer 3

-7 < x + 2 < 4.

You just want to isolate 'x' because that is what we are solving for....so to isolate 'x' here....we need to subtract 2 from everything

-7 < x + 2 < 4.
-2 -2 -2

*see how +2 -2 = 0 so it cancels out*

so we have

-9 < x < 2
