Equation:
interext + interest = interest
Amelia's parents and grandparents have both opened savings accounts to save for Amelia's education. This year, Amelia's parents' savings account earned 5% interest and her grandparent's account earned 8% interest. This year, the two savings accounts have earned a total of $460 in interest. At the beginning of the year, the two accounts were worth a total of $6500. Determine the current value of both saving accounts. Show all work necessary to justify your answer. 
0.05x + 0.08(6500-x) = 460

Multiply thru by 100 to get:

5x + 8(6500-x) = 46000
-3x + 8*6500 = 46000
-3x = -6000
x = $2000 (amt. invested at 5%)
6500-2000 = $4500 (amt. invested at 8%)
