[ 1/1 Equation]
    Work: Find the solution of equation 0.7 = (1×10.97+n×9.95)/(1+n) .
    Question type: Equation
    Solution:Original question:
     
7
10
= (1 ×
1097
100
+ n ×
199
20
) ÷ (1 + n )
     Multiply both sides of the equation by:(1 + n )
     
7
10
(1 + n ) = (1 ×
1097
100
+ n ×
199
20
)
    Remove a bracket on the left of the equation::
     
7
10
× 1 +
7
10
n = (1 ×
1097
100
+ n ×

)
    Remove a bracket on the right of the equation::
     
7
10
× 1 +
7
10
n = 1 ×
1097
100
+ n ×
199
20
    The equation is reduced to :
     
7
10
+
7
10
n =
1097
100
+ n ×
199
20

    Transposition :
     
7
10
n
199
20
n =
1097
100
7
10

    Combine the items on the left of the equation:
      -
37
4
n =
1097
100
7
10

    Combine the items on the right of the equation:
      -
37
4
n =
1027
100

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
      -
1027
100
=
37
4
n

    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 :
     
37
4
n = -
1027
100

    The coefficient of the unknown number is reduced to 1 :
      n = -
1027
100
÷
37
4
        = -
1027
100
×
4
37
        = -
1027
25
×
1
37

    We obtained :
      n = -
1027
925
    This is the solution of the equation.

    Convert the result to decimal form :
      n = - 1.11027
