    Work: Find the solution of equation 70%-15%+((1+X)/X)*8%*(1-37.5%) = 0 .
    Question type: Equation
    Solution:Original question:
     
70
100
15
100
+ ((1 + X ) ÷ X ) ×
8
100
(1

    Remove a bracket on the left of the equation::
     
70
100
15
100
+ (1 + X ) ÷ X ×
8
100
(1
75

) = 0
    The equation is reduced to :
     
11
20
+ (1 + X ) ÷ X ×
8
100
(1
75
200
) = 0
     Multiply both sides of the equation by: X
     
11
20
X + (1 + X ) ×
8
100
(1
75

20

    Combine the items on the right of the equation:
     
3
5
X = -
1
20

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