[ 1/1 Equation]
    Work: Find the solution of equation 100*13.7+10*22+x*30.1 = (100+x)*25 .
    Question type: Equation
    Solution:Original question:
     100 ×
137
10
 + 10 × 22 + x ×
301
10
 = (100 + x ) × 25
     Left side of the equation = 1370 + 220 + x ×
301
10
                                             = 1590 +
301
10
 x
    The equation is transformed into :
     1590 +
301
10
 x = (100 + x ) × 25
    Remove the bracket on the right of the equation:
     Right side of the equation = 100 × 25 + x × 25
                                               = 2500 + x × 25
    The equation is transformed into :
     1590 +
301
10
 x = 2500 + 25 x

    Transposition :
     
301
10
 x − 25 x = 2500 − 1590

    Combine the items on the left of the equation:
     
51
10
 x = 2500 − 1590

    Combine the items on the right of the equation:
     
51
10
 x = 910

    The coefficient of the unknown number is reduced to 1 :
      x = 910 ÷
51
10
        = 910 ×
10
51

    We obtained :
      x =
9100
51
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 178.431373
