:
Let x = lbs of pecan required
:
The weight of the final mixture = {x + 2)
:
5.60x + 3.50(2) = 4.34(x+2)
:
5.60x + 7 = 4.34x + 8.68
:
5.60x - 4.34x = 8.68 - 7
:
1.26x = 1.68
:
x =
x = 1 lbs required

Check solution a calc using decimals
enter: (5.6*1.333) + 7 = 14.465
enter: 4.34(1.333+2) = 14.465
