[ 1/1 Equation]
    Work: Find the solution of equation 142 = （X/(20*3.14））*（40*3.14）+X .
    Question type: Equation
    Solution:Original question:
     142 = ( X ÷ (20 ×
157
50
))(40 ×
157
50
) + X
    Remove a bracket on the right of the equation:：
     142 = X ÷ (20 ×
157
50
) × (40 ×
157
50
) + X
     Multiply both sides of the equation by:(20 ×
157
50
)
     142(20 ×
157
50
) = X (40 ×
157
50
) + X (20 ×
157
50
)
    Remove a bracket on the left of the equation:
     142 × 20 ×
157
50
 = X (40 ×
157
50
) + X (20 ×
157
50
)
    Remove a bracket on the right of the equation:：
     142 × 20 ×
157
50
 = X × 40 ×
157
50
 + X (20 ×
157
50
)
    The equation is reduced to :
     
44588
5
 = X ×
628
5
 + X (20 ×
157
50
)
    Remove a bracket on the right of the equation:：
     
44588
5
 =
628
5
 X + X × 20 ×
157
50
    The equation is reduced to :
     
44588
5
 =
628
5
 X + X ×
314
5
    The equation is reduced to :
     
44588
5
 =
942
5
 X

    Transposition :
      -
942
5
 X = -
44588
5

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     
44588
5
 =
942
5
 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 :
     
942
5
 X =
44588
5

    The coefficient of the unknown number is reduced to 1 :
      X =
44588
5
 ÷
942
5
        =
44588
5
 ×
5
942
        = 22294 ×
1
471

    We obtained :
      X =
22294
471
    This is the solution of the equation.

    By reducing fraction, we can get:
      X =
142
3

    Convert the result to decimal form :
      X = 47.333333
