[ 1/1 Equation]
    Work: Find the solution of equation 10/(10*(x+3.8)/(13.8+x)+10) = 2.73/12 .
    Question type: Equation
    Solution:Original question:
     10 ÷ (10( x +
19
5
) ÷ (
69
5
+ x ) + 10) =
273
100
÷ 12
     Multiply both sides of the equation by:(10( x +
19
5
) ÷ (
69
5
+ x ) + 10)
     10 =
273
100
÷ 12 × (10( x +
19
5
) ÷ (
69
5
+ x ) + 10)
    Remove a bracket on the right of the equation::
     10 =
273
100
÷ 12 × 10( x +
19
5
) ÷ (
69
5
+ x ) +
273
100
÷ 12 × 10
    The equation is reduced to :
     10 =
91
40
( x +
19
5
) ÷ (
69
5
+ x ) +
91
40
     Multiply both sides of the equation by:(
69
5
+ x )
     10(
69
5
+ x ) =
91
40
( x +

    The equation is reduced to :
     138 + 10 x =

x +
1001
25

    Transposition :
     10 x
91
20
x =
1001
25
138

    Combine the items on the left of the equation:
     
109
20
x =
1001
25
138

    Combine the items on the right of the equation:
     
109
20
x = -
2449
25

    The coefficient of the unknown number is reduced to 1 :
      x = -
2449
25
÷

    We obtained :
      x = -
9796
545
    This is the solution of the equation.

    Convert the result to decimal form :
      x = - 17.974312
