Find the system of equations to model the problem. DO NOT SOLVE THIS SYSTEM.
-If $9,000 is to be invested, part at 13% and the rest at 8% simple interest, how much should be invested at each
rate so that the total annual return will be the same as $9,000 invested at 9%? Set up a system of linear
equations, letting x1 be the amount invested at 13% and t 13% and be the amount invested at 8%.
