let x = pounds of coffee at 2$/pound
2.00X + 1.20 (3) = 1.76 (X+3)
2.00X + 3.60 = 1.76X + 5.28
.24X = 1.68
X = 7 pounds
6 (worth 12 units,) added to the 4 units gives 10 units worth 24. (This is the sort of problem we used to get at Primary school in the 1950's. It's probably University Entrance standard nowadays!)

Let x = pounds at 10/lb and Y = 30 pounds at 4/lb and Z = 30 +x = total pounds at 6/lb; then 10X + 4Y = 6Z solve for x 10x + 120 = 180 + 6x x = 15 pounds
