[ 1/1 Equation]
    Work: Find the solution of equation X = (7+1.54+X)*9% .
    Question type: Equation
    Solution:Original question:
      X = (7 +
77
50
 + X ) ×

    The equation is transformed into :
      X =
3843
5000
 +
9
100
 X

    Transposition :
      X −
9
100
 X =
3843
5000

    Combine the items on the left of the equation:
     
91
100
 X =
3843
5000

    The coefficient of the unknown number is reduced to 1 :
      X =
3843
5000
 ÷
91

    We obtained :
      X =
549
650
    This is the solution of the equation.

    Convert the result to decimal form :
      X = 0.844615
