100(x-5)=0.1的方程和验算

Answer 1

解方程:100(x-5)=0.1
100x-500=0.1
100x=0.1+500
100x=500.1
x=500.1/100
x=5.001。 验算如下:
将x=5.001代入原方程式解:
100(5.001-5)
=100x0.001=0.1验算完毕。

Answer 2

100(X-5)=0.1
10000(Ⅹ-5)=1
10000Ⅹ=50000+1=50001
X=5.0001
检验:
100(Ⅹ-5)=0.1
100(5.0001-5)=0.1
0.1=0.1

Answer 3

100（x-5）=0.1
100x-500=0.1
100x=0.1+500
100x=500.1
x=5.001

Answer 4

100x-500=0.1
100x=500+0.1
100x=500.1
x=500.1÷100
x=5.001

Answer 5

100(x－5)＝0.1
