[ 1/1 Equation]
    Work: Find the solution of equation 20x+(x/(2/3))*30 = 176.9 .
    Question type: Equation
    Solution:Original question:
     20 x + ( x ÷ (2 ÷ 3)) × 30 =
1769
10
    Remove a bracket on the left of the equation:：
     20 x + x ÷ (2 ÷ 3) × 30 =
1769
10
     Multiply both sides of the equation by:(2 ÷ 3)
     20 x (2 ÷ 3) + x × 30 =
1769
10
(2 ÷ 3)
    Remove a bracket on the left of the equation:
     20 x × 2 ÷ 3 + x × 30 =
1769
10
(2 ÷ 3)
    Remove a bracket on the right of the equation:：
     20 x × 2 ÷ 3 + x × 30 =
1769
10
 × 2 ÷ 3
    The equation is reduced to :
     
40
3
 x + x × 30 =
1769
15
    The equation is reduced to :
     
130
3
 x =
1769
15

    The coefficient of the unknown number is reduced to 1 :
      x =
1769
15
 ÷

130

    We obtained :
      x =
1769
650
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 2.721538
