[ 1/1 Equation]
    Work: Find the solution of equation x+(2x-4)+(x-6) = 20 .
    Question type: Equation
    Solution:Original question:
      x + (2 x 4) + ( x 6) = 20
    Remove the bracket on the left of the equation:
     Left side of the equation = x + 2 x 4 + ( x 6)
                                             = 3 x 4 + ( x 6)
                                             = 3 x 4 + x 6
                                             = 4 x 10
    The equation is transformed into :
     4 x 10 = 20

    Transposition :
     4 x = 20 + 10

    Combine the items on the right of the equation:
     4 x = 30

    The coefficient of the unknown number is reduced to 1 :
      x = 30 ÷ 4
        = 30 ×
1
4
        = 15 ×
1
2

    We obtained :
      x =
15
2
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 7.5
