------------------------
c + h = 60 (60 lbs of cashews and hazelnuts)
650h + 450c = 60*510 --> 13h + 9c = 612 (divide by 50)
c = 60-h (from 1st eqn)
Sub for c into 2nd eqn
13h + 9*(60-h) = 612
13h + 540 - 9h = 612
4h = 72
h = 18 lbs of hazelnuts
c = 42 pounds of cashews

let h=hazelnuts and c=cashews
"If Jackie wants 60 pounds total os mixture" ___ h+c=60 ___ c=60-h
"Hazelnuts cost $6.50 per pound and cashews cost $4.50 per pound"
for mixture ___ "and the cost to be $5.10 per pound"
h(6.50) + c(4.50) = 60(5.10)
substituting and multiplying by 10 ___ 65h + 45(60-h) = 3060
___ 65h + 2700 - 45h = 3060
___ 20h = 360
___ h=18
substituting ___ c = 60 - (18) ___ c = 42
