[ 1/1 Equation]
    Work: Find the solution of equation （x-1）/（x+2） = （4*3.14*45.3852）/（3*945.0957） .
    Question type: Equation
    Solution:Original question:
     ( x − 1) ÷ ( x + 2) = (4 ×
157
50
 ×
113463
2500
) ÷ (3 ×
9450957
10000
)
     Multiply both sides of the equation by:( x + 2) ,  (3 ×
9450957
10000
)
     ( x − 1)(3 ×
9450957
10000
) = (4 ×

)( x + 2)
    Remove a bracket on the left of the equation:：
      x (3 ×
9450957
10000
) − 1(3 ×
9450957
