[ 1/1 Equation]
    Work: Find the solution of equation x(1+0.3)-1.1x(1+0.2) = 6 .
    Question type: Equation
    Solution:Original question:
      x (1 +

    Remove the bracket on the left of the equation:
     Left side of the equation = x × 1 + x ×

    The equation is transformed into :
      -
1
50
 x = 6

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
      - 6 =
1
50
 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 :
     
1
50
 x = - 6

    The coefficient of the unknown number is reduced to 1 :
      x = - 6 ÷
1
50
        = - 6 × 50

    We obtained :
      x = - 300
    This is the solution of the equation.
