Question

5 < x – 2 < 11

Answer 1

x>5 and x<13

Answer 2

you can split this into x-2 > 5 and x-2 < 11
and solve separately

Answer 3

No need to split anything. Just do this:

5 < x – 2 < 11
5 + 2 < x < 11 + 2
7 < x < 13

Answer 4

Now we know that x is between 7 and 13

Answer 5

that works, but it's sometimes hard to visualize with both the inequality signs in the equation, just nice to have it out for clarification

Answer 6

It's also easy to see that x is between the two numbers you are solving for

Answer 7

Yep both way works, just depends on how your brain operates
