[ 1/1 Equation]
    Work: Find the solution of equation 71x/(100+90x-20) = (71x+4.4)/(105.6+9x) .
    Question type: Equation
    Solution:Original question:
     71 x ÷ (100 + 90 x 20) = (71 x +
22
5
) ÷ (
528
5
+ 9 x )
     Multiply both sides of the equation by:(100 + 90 x 20) ,  (
528
5
+ 9 x )
     71 x (
528
5
+ 9 x ) = (71 x +
22
5
)(100 + 90 x 20)
    Remove a bracket on the left of the equation::
     71 x ×
528
5
+ 71 x × 9 x = (71 x +
22
5
)(100 + 90 x 20)
    Remove a bracket on the right of the equation::
     71 x ×
528
5
+ 71 x × 9 x = 71 x (100 + 90 x 20) +
22
5
(100 + 90 x 20)
    The equation is reduced to :
     
37488
5
x + 639 x x = 71 x (100 + 90 x 20) +
22
5
(100 + 90 x 20)
    Remove a bracket on the right of the equation::
     
37488
5
x + 639 x x = 71 x × 100 + 71 x × 90 x 71 x × 20 +
22
5
(100 + 90 x 20)
    The equation is reduced to :
     
37488
5
x + 639 x x = 7100 x + 6390 x x 1420 x +
22
5
(100 + 90 x 20)
    The equation is reduced to :
     
37488
5
x + 639 x x = 5680 x + 6390 x x +
22
5
(100 + 90 x 20)
    Remove a bracket on the right of the equation::
     
37488
5
x + 639 x x = 5680 x + 6390 x x +
22
5
× 100 +
22
5
× 90 x
22
5
× 20
    The equation is reduced to :
     
37488
5
x + 639 x x = 5680 x + 6390 x x + 440 + 396 x 88
    The equation is reduced to :
     
37488
5
x + 639 x x = 6076 x + 6390 x x + 352
    
    There are 0 solution(s).
