Ivanna bought a desktop computer and a laptop computer. 

 the laptop cost $450 more than the desktop.

laptop price (x+450)
 For the desktop the interest rate was 9% per year,

and for the laptop it was 6% per year. 
Interest = 6%(x+450)

The total finance charges for one year were $300. 
9%x + 6%(x+450) = 300
9x+6(x+450) = 300*100
9x+6x +2700=30000
15x= 30000-2700
15x=27300
x= 1820
