1. At first, my brother was going to move x pieces
for the first time:
Brother: X brother: 26-x
The second time:
Brother: X / 2 brother: 26-x + X / 2 = 26-x / 2
third time:
Brother: X / 2 + (26-x / 2) / 2 = 13 + X / 4 brother: (26-x / 2) / 2 = 13-x / 4
The fourth time:
Brother: 13 + X / 4-5 brother: 13-x / 4 + 5
13-x/4+5-(13+x/4-5)=2
-x/2+10=2
x=16
At first, my brother was going to move 16 yuan
There are x apples in this basket
(x/2-1)/2+1=3
x=10
There are ten apples in this basket
3.11/16,17/24,21/32
4. The score was originally X / y
x+y=20
x/(y-8)=1
x=14
x=6
The score turned out to be 6 / 14
