Howdy! I have a question on my homework that I do not understand, would anyone be able to help? Ruth invests $10,000 in two accounts. One account has an annual interest rate of 7% and the other has 5%. Let I represent the total interest earned in one year. Than Ruth's investment can be modelled by the system of equations x+y=10,000 and 0.07x+0.05y=I

Determine the solution for this system of equations that represents the possible investment and find the value of I that corresponds to your solution.

Find the solution for the system if I = 800. Explain why this solution does not represent a possible investment.
