I understand that so much better then the last person that helped. could you do the same thing but swap the equation out for -2x=8y instead of x=5

I asked this question earlier but was still very confused on how to solve the problem. If you can please write out step by step and show exactly how to solve this problem it would help give me a more clear visual way on how to solve this. Thank you. QUESTION:

Why do you think we should learn about quadratic equations? how are they different from linear equations, and what is the significance of quadratic equation in the business world. Make sure you provide very specific examples to help us understand your explanation.
