To the shops brought together 23.2 kg of goods, fruits, vegetables and nuts. fruit was 4.7 kg more than vegetables, nuts was 1.5 kg less than the fruit. Determine the amount of fruits, vegetables and nuts.

Correct result:

a =  9.8
b =  5.1
c =  8.3

Solution:


a+b+c=23.2
a = 4.7+b
c = a-1.5

a+b+c = 23.2
a-b = 4.7
a-c = 1.5

a = 49/5 = 9.8
b = 51/10 = 5.1
c = 83/10 = 8.3
