# The bakery

The bakery delivered 60 kg of bread to the store, the breads weighed 1 kg and 2 kg, a total of 35 pieces. How many loaves weighed 1 kg and how many were two-kilo loaves?

a =  10
b =  25

### Step-by-step explanation:

60 = 1a+2b
a+b = 35

60 = 1•a+2•b
a+b = 35

a+2b = 60
a+b = 35

a = 10
b = 25
