[ 1/1 Equation]
    Work: Find the solution of equation (x/2.7)+((456-x)/8.9) = 100 .
    Question type: Equation
    Solution:Original question:
     ( x ÷
27
10
) + ((456 − x ) ÷
89
10
) = 100
    Remove the bracket on the left of the equation:
     Left side of the equation = x ÷
27
10
 + ((456 − x ) ÷
89

)
                                             =

    The equation is transformed into :
     
620
2403
 x +
4560
89
 = 100

    Transposition :

 x = 100 −
4560
89

    Combine the items on the right of the equation:
     
620
2403
 x =
4340
89

    The coefficient of the unknown number is reduced to 1 :
      x =
4340
89
 ÷

        = 7 × 27

    We obtained :
      x = 189
    This is the solution of the equation.
