✔ 最佳答案
20%x(15+10)=5因為25的20%是5所以Y是15

20%x(y+10)=5
20%(xy+10x)=5
xy+10x=5/20%
xy+10x=25
x=1 , y=15
20%(xy+10x)=5
xy+10x=5/20%
xy+10x=25
x=1 , y=15

I think you mean
20%*(y+10)=5
y + 10 = 5 / (20/100)
y + 10 = 5 * (100/20)
y + 10 = 25
y = 25 - 10
y = 15

> 20/100x(y+10)=5
>(y+10)=5x100/20
>y+10=25
>y=25-10
>y=15
> 20/100x(y+10)=5
>(y+10)=5x100/20
>y+10=25
>y=25-10
>y=15

唔知你用%點解，係電腦上%係求餘數
20%x(y+10)=5
x(y+10)=15
當:
x=1, y=5
x=3, y=-5
x=5, y=-7
x=15, y=-9
20%x(y+10)=5
x(y+10)=15
當:
x=1, y=5
x=3, y=-5
x=5, y=-7
x=15, y=-9
