[ 1/1 Equation]
    Work: Find the solution of equation 42x+50(50-x) = 2100 .
    Question type: Equation
    Solution:Original question:
     42 x + 50(50 x ) = 2100
    Remove the bracket on the left of the equation:
     Left side of the equation = 42 x + 50 × 5050 x
                                             = 42 x + 250050 x
                                             = - 8 x + 2500
    The equation is transformed into :
      - 8 x + 2500 = 2100

    Transposition :
      - 8 x = 21002500

    Combine the items on the right of the equation:
      - 8 x = - 400

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     400 = 8 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 :
     8 x = 400

    The coefficient of the unknown number is reduced to 1 :
      x = 400 ÷ 8
        = 400 ×
1
8
        = 50 × 1

    We obtained :
      x = 50
    This is the solution of the equation.
