[ 1/1 Equation]
    Work: Find the solution of equation 161.5*7.91+13.1x = (161.5+x)*8 .
    Question type: Equation
    Solution:Original question:
     
323
2
×
791
100
+
131
10
x = (
323
2
+ x ) × 8
     Left side of the equation =
255493
200
+
131
10
x
    The equation is transformed into :
     
255493
200
+
131
10
x = (
323
2
+ x ) × 8
    Remove the bracket on the right of the equation:
     Right side of the equation =
323
2
× 8 + x × 8
                                               = 1292 + x × 8
    The equation is transformed into :
     
255493
200
+
131
10
x = 1292 + 8 x

    Transposition :
     
131
10
x 8 x = 1292
255493
200

    Combine the items on the left of the equation:
     
51
10
x = 1292
255493
200

    Combine the items on the right of the equation:
     
51
10
x =
2907
200

    The coefficient of the unknown number is reduced to 1 :
      x =
2907
200
÷

51
        =
57
20
× 1

    We obtained :
      x =
57
20
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 2.85
