Question

What is the solution set of |2x + 4| < 10
I know how to find solution sets I'm just unsure of what the <10 means, could somebody please explain it

Answer 1

<10 means less than 10

Answer 2

it also means your answer will have one interval and not two

Answer 3

which is due to the modulus

Answer 4

so you should start with
\[-10<2x+4<10\] and solve in two steps
1) subtract 4 all the way across
2) divide by 2 (all the way across)

Answer 5

Thank you :)
