Advanced Mathematics Problem Solving (Applied Algebra)

I am seeking a freelancer with expertise in advanced mathematics problem solving, specifically in the field of applied algebra. The ideal candidate will have a strong understanding of linear equations, quadratic equations, and systems of equations. And a lot more of Applied Mathematics knowledge.

There are only 6-7 questions I need help with.

Skills and Experience:
- Proficiency in advanced algebra and problem-solving techniques
- Experience solving complex mathematical problems in applied algebra
- Ability to provide step-by-step solutions for advanced-level problems
- Provide the final answer
- Strong analytical skills and attention to detail
- Excellent communication skills to clearly explain the problem-solving process.

I will attach a PDF of example problems for you to look over and get an idea of what the questions will look like. If you can't answer the example problems, do not apply for this job.

Thanks
