    How could I set this word problem up as a system?

    A system of linear equations that is. I think it would be easier to solve that way. The problem:

    Mrs. Brady invests a total of $6913 in two savings accounts. One account yields 7% simple interest and the other 7.5% simple interest. She would like to find the amount placed in each account if a total of $511.92 in interest is received after one year.

    Hi

    Here is a hint to get you started:

    x+y=6913 0.07x+0.075y=511.92

    Can you take it from there?
