The uploaded image contains multiple math exercises in French, covering a range of topics including algebra, inequalities, intervals, and simplifications. I'll process and analyze one of the exercises for you or provide solutions to specific questions if you specify.

• If you'd like a detailed explanation for a particular part of an exercise.

For example:
