[ 1/1 Equation]
    Work: Find the solution of equation 2.5 = x*(1+0.05)/(1-0.056) .
    Question type: Equation
    Solution:Original question:
     
5
2
= x (1 +
1
20
) ÷ (1 -
7
125
)
     Multiply both sides of the equation by:(1 -
7
125
)
     
5
2
(1 -
7
125
) = x (1 +
1
20
)
    Remove a bracket on the left of the equation::
     
5
2

    The equation is reduced to :
     
5
2
-
7
50
= x × 1 + x ×
1
20
    The equation is reduced to :
     
59
25
=
21
20
x

    Transposition :
      -
21
20
x = -
59
25

    Multiply both sides of the equation by -1 :
     
21
20
x =
59
25

    The coefficient of the unknown number is reduced to 1 :
      x =
59
25
÷

    Get the solution of the equation :
      x =
236
105

    Convert the result to decimal form :
      x = 2.247619
