[ 1/1 Equation]
    Work: Find the solution of equation X*0.1378+(0.2X-0.0078X)*0.025 = 700000 .
    Question type: Equation
    Solution:Original question:
      X ×

200000
 X
    The equation is transformed into :
     
28521
200000
 X = 700000

    The coefficient of the unknown number is reduced to 1 :
      X = 700000 ÷
28521
200000
        = 700000 ×
200000
28521

    We obtained :
      X =
140000000000
28521
    This is the solution of the equation.
