[ 1/1 Equation]
    Work: Find the solution of equation 3x+4+(99-x)*0.25 = 100 .
    Question type: Equation
    Solution:Original question:
     3 x + 4 + (99 x ) ×
1
4
= 100
    Remove the bracket on the left of the equation:
     Left side of the equation = 3 x + 4 + 99 ×
1
4
x ×

    The equation is transformed into :
     
11
4
x +
115
4
= 100

    Transposition :

    Combine the items on the right of the equation:
     
11
4
x =
285
4

    The coefficient of the unknown number is reduced to 1 :
      x =
285
4
÷
11
4
        =

11
        = 285 ×
1
11

    We obtained :
      x =
285
11
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 25.909091
