Question

1500=10000×(1-0.05)-300×10000÷X怎解呢

1500=10000×(1-0.05)-300×10000÷X怎解呢

Answer 1

先去两个0
15＝100（1-0.05）-300000/X
15＝95-30000/X
80X-300000＝0
X＝3750

谢谢你？

Answer 2

X = [ 10000 x ( 1 - 0.05 ) - 1500 ] / ( 300 x 10000 )
= ( 9500 - 1500 ) / 3000000
= 8000 / 3000000
= 8 / 3000
= 0.002666666666667

看错最后的符号了😂

( 300 x 10000 ) / X = 10000 x ( 1 - 0.05 ) - 1500
3000000 / X = 9500 - 1500
3000000 / X = 8000
X = 3000000 x 8000

24 000 000 000
24 billions

( 300 x 10000 ) / X = 10000 x ( 1 - 0.05 ) - 1500
3000000 / X = 9500 - 1500
3000000 / X = 8000
X = 3000000 / 8000
X = 375
在手机上写数学太乱了，不断算错😭

还是习惯在纸上写
