Beginning 2879

Juro, Fero, and Michael played bullets. In the beginning, everyone had the same number. In the first game, Juro won 4 bullets, and Fero 5 (that means Michael lost nine bullets). Michael won 7 balls in the second game, and Fero lost four. Michael lost three bullets in the third game, and Juro lost two.
Find out if he had more Juro or Michael bullets at the end. How much more?

Correct answer:

d =  4
f =  6
j =  -1
m =  -5

Step-by-step explanation:


j = +4-3-2
f = +5-4+5
m = -9+7-3
d = j-m

j = -1
f = 6
m = -5
d-j+m = 0

Pivot: Row 1 ↔ Row 4
d-j+m = 0
f = 6
m = -5
j = -1

Pivot: Row 3 ↔ Row 4
d-j+m = 0
f = 6
j = -1
m = -5


m = -5/1 = -5
j = -1/1 = -1
f = 6/1 = 6
d = 0+j-m = 0-1+5 = 4

d = 4
f = 6
j = -1
m = -5
