[ 1/1 Equation]
    Work: Find the solution of equation 3.14*(670*670-74*74) = 1485000*4*X .
    Question type: Equation
    Solution:Original question:
     
157
50
(670 × 670 − 74 × 74) = 1485000 × 4 X
    Remove the bracket on the left of the equation:
     Left side of the equation =
157
50
 × 670 × 670 −
157
50
 × 74 × 74
                                             = 1409546 −
429866

    The equation is transformed into :
     
34808784
25
 = 1485000 × 4 X
     Right side of the equation = 5940000 X
    The equation is transformed into :
     
34808784
25
 = 5940000 X

    If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
     5940000 X =
34808784
25

    The coefficient of the unknown number is reduced to 1 :
      X =
34808784
25
 ÷ 5940000
        =
34808784

    We obtained :
      X =
725183
3093750
    This is the solution of the equation.

    Convert the result to decimal form :
      X = 0.234403
