[ 1/1 Equation]
    Work: Find the solution of equation 720-12x/5+2x = 130 .
    Question type: Equation
    Solution:Original question:
     72012 x ÷ 5 + 2 x = 130
     Left side of the equation = 720
12
5
x + 2 x
                                             = 720
2
5
x
    The equation is transformed into :
     720
2
5
x = 130

    Transposition :
      -
2
5
x = 130720

    Combine the items on the right of the equation:
      -
2
5
x = - 590

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     590 =
2
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 :
     
2
5
x = 590

    The coefficient of the unknown number is reduced to 1 :
      x = 590 ÷
2
5
        = 590 ×
5
2
        = 295 × 5

    We obtained :
      x = 1475
    This is the solution of the equation.
