Question

4│x + 5│ - 2 ≤ 10 How do you solve this ???

Answer 1

well , these lines ----> | xxx | mean absolute value so you should know what to do there :]

Answer 2

use this theorem: if \(b\geq0\),
\[ \large |a|\leq b\quad\Leftrightarrow -b\leq a\leq b \]

Answer 3

so like the first step i think you can assuming to the both sides 2

and like step 2. so i think you will can divide both sides by 4

and after that check what will get

hope so much that you can calculi these two steps

so wait your reply with this work

good luck
