[ 1/1 Equation]
    Work: Find the solution of equation (x+2)/121 = (x+109)/122 .
    Question type: Equation
    Solution:Original question:
     ( x + 2) ÷ 121 = ( x + 109) ÷ 122
    Remove the bracket on the left of the equation:
     Left side of the equation = x ×
1
121
 + 2 ×
1
121
                                             = x ×

    The equation is transformed into :
     
1
121
 x +
2
121
 = ( x + 109) ÷ 122
    Remove the bracket on the right of the equation:
     Right side of the equation = x ×

    Combine the items on the right of the equation:
     
1
14762
 x =
12945
14762

    The coefficient of the unknown number is reduced to 1 :
      x =
12945
14762
 ÷
1
14762
        =
12945
14762
 × 14762
        = 12945 × 1

    We obtained :
      x = 12945
    This is the solution of the equation.
