Answer 1

-7 ≤ x ≤ 11

Explanation:

Given the inequality:

`\displaystyle{5 \leq x + 12 \leq 23}`

In order to solve this kind of inequality, similiar method, you isolate the x-term by subtracting every sides by 12. Therefore,

`\displaystyle{5-12 \leq x+12-12 \leq 23-12}\\\\\displaystyle{-7\leq x \leq 11}`

Therefore, the interval is -7 ≤ x ≤ 11
