[ 1/1 Equation]
    Work: Find the solution of equation 0.05 = (2+(4/69+X)*50)/(90+90X) .
    Question type: Equation
    Solution:Original question:
     
1
20
 = (2 + (4 ÷ 69 + X ) × 50) ÷ (90 + 90 X )
     Multiply both sides of the equation by:(90 + 90 X )
     
1
20
(90 + 90 X ) = (2 + (4 ÷ 69 + X ) × 50)
    Remove a bracket on the left of the equation:：
     
1
20
 × 90 +
1
20
 × 90 X = (2 + (4 ÷ 69 + X ) × 50)
    Remove a bracket on the right of the equation:：
     
1
20
 × 90 +

20
 × 90 X = 2 + (4 ÷ 69 + X ) × 50
    The equation is reduced to :

 X = 2 + (4 ÷ 69 + X ) × 50
    Remove a bracket on the right of the equation:：

 X = 2 + 4 ÷ 69 × 50 + X × 50
    The equation is reduced to :

    Combine the items on the left of the equation:
      -

    Combine the items on the right of the equation:
      -
91
2
 X =
55
138

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
      -
55
138
 =
91
2
 X

    If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
     
91
2
 X = -

138

    The coefficient of the unknown number is reduced to 1 :
      X = -

    This is the solution of the equation.

    Convert the result to decimal form :
      X = - 0.008759
