[ 1/1 Equation]
    Work: Find the solution of equation 100/x = (1+100x)*(1+0.0025x) .
    Question type: Equation
    Solution:Original question:
     100 ÷ x = (1 + 100 x )(1 +
1
400
x )
     Multiply both sides of the equation by: x
     100 = (1 + 100 x )(1 +
1
400
x ) x
    Remove a bracket on the right of the equation::
     100 = 1(1 +
1
400
x ) x + 100 x (1 +
1
400
x ) x
    Remove a bracket on the right of the equation::
     100 = 1 × 1 x + 1 ×
1
400
x x + 100 x (1 +
1
400
x ) x
    The equation is reduced to :
     100 = 1 x +
1
400
x x + 100 x (1 +
1
400
x ) x
    Remove a bracket on the right of the equation::
     100 = 1 x +
1
400
x x + 100 x × 1 x + 100 x ×
1
400
    The equation is reduced to :
     100 = 1 x +
1
400
x x + 100 x x +
1
4
x x x

    The solution of the equation:
        x1≈-1.006273 , keep 6 decimal places
        x2≈0.993773 , keep 6 decimal places
    
    There are 2 solution(s).
