-----
Let price of peanuts be x cents per lb.; 4lbs cost 4x cents
Walnuts cost (x+20) cents per lb. ; 6 lbs cost 6(x+20) cents
------------
EQUATION:
value + value = 510 cents
4x + 6(x+20) = 510
4x + 6x + 120 = 510
10x = 390
x = 39 cents ( price of peanuts per lb.)
x+20 = 59 cents ( price of walnuts per lb.)
