Three dice

When you throw three dice was, the sum total of the dice 10. The yellow dice fell one eye more than on the red, and brown fell three eyes less than red. How many eyes fell on every dice?

Correct answer:

a =  5
b =  4
c =  1

Step-by-step explanation:


a+b+c=10
a = b+1
c=b-3

a+b+c = 10
a-b = 1
b-c = 3

Row 2 - Row 1 → Row 2
a+b+c = 10
-2b-c = -9
b-c = 3

Row 3 - 1/-2 · Row 2 → Row 3
a+b+c = 10
-2b-c = -9
-1.5c = -1.5


c = -1.5/-1.5 = 1
b = -9+c/-2 = -9+1/-2 = 4
a = 10-b-c = 10-4-1 = 5

a = 5
b = 4
c = 1
