[ 1/1 Equation]
    Work: Find the solution of equation （4500x12x0.9-60%×70X×（4.9%+2%））÷（40%x70X+5%×70X） = 0 .
    Question type: Equation
    Solution:Original question:
     (4500 x × 12 x ×
9
10
 −
60
100
 × 70 x (
49
1000
 +
2
100
)) ÷ (
40
100
 x × 70 x +
5
100
 × 70 x ) = 0
     Multiply both sides of the equation by:(
40
100
 x × 70 x +
5
100
 × 70 x )
     (4500 x × 12 x ×
9
10
 −
60
100
 × 70 x (
49
1000
 +

)) = 0
    Remove a bracket on the left of the equation:：
     4500 x × 12 x ×
9
10
 −
60
100
 × 70 x (
49
1000
 +
2
100
) = 0
    The equation is reduced to :
     48600 x x − 42 x (
49
1000
 +
2
100
) = 0
    Remove a bracket on the left of the equation:
     48600 x x − 42 x ×
49
1000
 − 42 x ×
2
100
 = 0
    The equation is reduced to :
     48600 x x −
1029
500
 x −
21
25
 x = 0
    The equation is reduced to :
     48600 x x −
1449
500
 x = 0
    
    There are 0 solution(s).
