Isabella has twice as much money invested at 4% as she has invested at 3%, and she has $500 more invested at 5% than she has at 3%. If the annual income from these three investments is $2025, how much does she have invested at 4%?

.04(2x)+.03(x)+.05(500+x)=2025

.08x+.03x+.05x+25=2025

.16x+25=2025

.16x=2000

x=12500

She has 2x invested at 4%, so she had $25000.00 invested at 4%.
