[ 1/1 Equation]
    Work: Find the solution of equation (3.7*x+89.7)/(26+x) = 3.5 .
    Question type: Equation
    Solution:Original question:
     (
37
10
 x +
897
10
) ÷ (26 + x ) =
7
2
     Multiply both sides of the equation by:(26 + x )
     (
37
10
 x +
897
10
) =
7
2
(26 + x )
    Remove a bracket on the left of the equation:：
     
37
10
 x +
897
10
 =
7
2
(26 + x )
    Remove a bracket on the right of the equation:：
     
37
10
 x +
897
10
 =
7
2
 × 26 +
7
2
 x
    The equation is reduced to :
     
37
10
 x +
897
10
 = 91 +
7
2
 x

    Transposition :
     
37
10
 x −
7
2
 x = 91 −
897
10

    Combine the items on the left of the equation:
     
1
5
 x = 91 −
897
10

    Combine the items on the right of the equation:
     
1
5
 x =
13
10

    The coefficient of the unknown number is reduced to 1 :
      x =
13
10
 ÷
1
5
        =
13
10
 × 5
        =
13
2
 × 1

    We obtained :
      x =
13
2
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 6.5
