[ 1/1 Equation]
    Work: Find the solution of equation (2x+x+2x-15+(2x-15)*3)*5/6 = 76*6 .
    Question type: Equation
    Solution:Original question:
     (2 x + x + 2 x − 15 + (2 x − 15) × 3) × 5 ÷ 6 = 76 × 6
     Left side of the equation = (2 x + x + 2 x − 15 + (2 x − 15) × 3) ×

6
    The equation is transformed into :
     (2 x + x + 2 x − 15 + (2 x − 15) × 3) ×

 x − 50
    The equation is transformed into :
     
55
6
 x − 50 = 76 × 6
     Right side of the equation = 456
    The equation is transformed into :
     
55
6
 x − 50 = 456

    Transposition :
     
55
6
 x = 456 + 50

    Combine the items on the right of the equation:
     
55
6
 x = 506

    The coefficient of the unknown number is reduced to 1 :
      x = 506 ÷
55
6
        = 506 ×

    This is the solution of the equation.

    Convert the result to decimal form :
      x = 55.2
