[ 1/1 Equation]
    Work: Find the solution of equation (x*155+35*41)/(155+35) = 25 .
    Question type: Equation
    Solution:Original question:
     ( x × 155 + 35 × 41) ÷ (155 + 35) = 25
     Multiply both sides of the equation by:(155 + 35)
     ( x × 155 + 35 × 41) = 25(155 + 35)
    Remove a bracket on the left of the equation::
      x × 155 + 35 × 41 = 25(155 + 35)
    Remove a bracket on the right of the equation::
      x × 155 + 35 × 41 = 25 × 155 + 25 × 35
    The equation is reduced to :
      x × 155 + 1435 = 3875 + 875
    The equation is reduced to :
     155 x + 1435 = 4750

    Transposition :
     155 x = 47501435

    Combine the items on the right of the equation:
     155 x = 3315

    The coefficient of the unknown number is reduced to 1 :
      x = 3315 ÷ 155
        = 3315 ×
1
155
        = 663 ×
1
31

    We obtained :
      x =
663
31
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 21.387097
