    Work: Find the solution of equation 200*1201+1/3*x+280*(1-3/7*x)*80*(1+2*x) = 46400*(1+24/29*x) .
    Question type: Equation
    Solution:Original question:
     200 × 1201 + 1 ÷ 3 × x + 280(13 ÷ 7 × x ) × 80(1 + 2 x ) = 46400(1 + 24 ÷ 29 × x )
     Left side of the equation = 240200 +
1
3
x + 22400(13 ÷ 7 × x )(1 + 2 x )
    The equation is transformed into :
     240200 +
1
3
x + 22400(13 ÷ 7 × x )(1 + 2 x ) = 46400(1 + 24 ÷ 29 × x )
    Remove the bracket on the left of the equation:
     Left side of the equation = 240200 +

3
x + 22400 × 1(1 + 2 x )22400 × 3 ÷ 7 × x (1 + 2 x )
                                             = 240200 +

x + 22400(1 + 2 x )9600 x (1 + 2 x )
                                             = 240200 +

x + 22400 × 1 + 22400 × 2 x 9600 x (1 + 2 x )
                                             = 240200 +

x 19200 x x
    The equation is transformed into :
     262600 +
105601
3
x 19200 x x = 46400(1 + 24 ÷ 29 × x )
    Remove the bracket on the right of the equation:
     Right side of the equation = 46400 × 1 + 46400 × 24 ÷ 29 × x
                                               = 46400 + 38400 x
    The equation is transformed into :
     262600 +
105601
3
x 19200 x x = 46400 + 38400 x

    The solution of the equation:
        x1≈-3.440013 , keep 6 decimal places
        x2≈3.273364 , keep 6 decimal places
    
    There are 2 solution(s).
