Answer:

5 Kg

Step-by-step explanation:

Let:

The number of kilograms of pecan is x

The number of kilograms of cashew is y

2.7x + 2.5y = 28.7 --------Equation 1

x = y - 1 -----------------------Equation 2

Put the values of y  

2.7(y - 1) + 2.5y = 28.7

2.7y + 2.7 + 2.5y = 28.7

5.2y = 26

y = 5 kg
