- Create an equation to find y: 3 =
- Calculate by adding: 3 =
- Multiply both sides of the equation by 7 : 21 = y - 2
- Move the variable to the left-hand side and change its sign : -y + 21 = -2
- Calculate and change signs : y = 23
y = 23

Answer: The answer is 13 ponds of each type should be used.
Step-by-step explanation: Given that the coffee counter charges $11.00 per pound for kenyan french roast coffee and $13.00 per pound for sumatra coffee. We are to find the quantity of each type that should be used to make a 26 pound blend that sells for $12.00 per pound.
Let 'x' pound and 'y' pound of kenyan french roast coffee and sumatra coffee be used in the mixture of 26 pound.
So, we have
Multiplying equation (A) by 11 and subtracting from equation (B), we have
and from equation (A),
Thus, 13 pounds of each type of coffee should be used.
