.04x+.045(2x)= 1430
.04x+.09x = 1430
1.3x = 1430
x = 1100
~~~~~~~~~~~~~~~~~~~~~~~~
1100/.04 = 27,500 is how much she has invested at 4% and
1430-1100 = 330/.045 = 7,333.33 is invested at 4.5%
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Check:
27500*.04 = 1100
7333.33*.045 = 330
1100+330 = 1430 We have the right answer
