Answer: 13

Step-by-step explanation:

Add 3 to each side. That original 3 is cancelled out so you're left with 4x=11. Divide each side by 4 and that leaves you with x = 3.5

Now all you have to do is multiply 4 by 3.5 which is 14. You now have to subtract 1 and your answer is 13.

The Coffee Counter charges $8 per pound for Kenyan French Roast coffee and $7 per pound for Sumatran coffee.

spayn [35]

Answer:

Kenyan French Roast coffee x=6

Sumatran coffee y=14

Step-by-step explanation:

x+y=20 blend coffee

8x+7y=7.3(20) selling price

x+y=20 ⇒ x=20-y

substitute in the equation:

8x+7y=7.3(20)

8(20-y)+7y=7.3(20) for 20 pound blend

160-8y+7y=146

-y=146-160

y=14 pond

x+y=20

x=20-14=6

check : 14*7+6(8)=146/7.3=20 pound
