Crates 2

In 6 crates is 45 kg of apples
In  5 crates is equally
In 1 in crate is 3 kg more

How many kilograms in each crate?

Correct result:

a =  7 kg
b =  7 kg
c =  7 kg
d =  7 kg
e =  7 kg
f =  10 kg

Solution:


a+b+c+d+e+f=45
a=b
a=c
a=d
a=e
f=a+3

a+b+c+d+e+f = 45
a-b = 0
a-c = 0
a-d = 0
a-e = 0
a-f = -3

a = 7
b = 7
c = 7
d = 7
e = 7
f = 10
