    Work: Find the solution of equation 70% = (X+40%+9%+7%)+4.5%(X+40%+9%+7%) .
    Question type: Equation
    Solution:Original question:

    Remove the bracket on the right of the equation:
     Right side of the equation = X +

                                               =
209
200
X +
1463
2500
    The equation is transformed into :
     
70
100
=
209
200
X +
1463
2500

    Transposition :
      -
209
200
X =
1463
2500
70
100

    Combine the items on the right of the equation:
      -
209
200
X = -
287
2500

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     
287
2500
=
209
200
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 :
     
209
200
X =
287
2500

    The coefficient of the unknown number is reduced to 1 :
      X =
287
2500
÷
209
200
        =
287
2500
×
200
209
        =
287
25
×
2
209

    We obtained :
      X =
574
5225
    This is the solution of the equation.

    Convert the result to decimal form :
      X = 0.109856
