[ 1/1 Equation]
    Work: Find the solution of equation (199+240)/30*x+226/30*(x+15)+120/30(x+30) = 1593 .
    Question type: Equation
    Solution:Original question:
     (199 + 240) ÷ 30 × x + 226 ÷ 30 × ( x + 15) + 120 ÷ 30 × ( x + 30) = 1593
     Left side of the equation = (199 + 240) ×

 x + 233
    The equation is transformed into :
     
157
6
 x + 233 = 1593

    Transposition :
     
157
6
 x = 1593 − 233

    Combine the items on the right of the equation:
     
157
6
 x = 1360

    The coefficient of the unknown number is reduced to 1 :
      x = 1360 ÷
157
6
        = 1360 ×
6
157

    We obtained :
      x =
8160
157
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 51.974522
