[ 1/1 Equation]
    Work: Find the solution of equation (160+383.5)/30*x+107/30*(x+15)+120/30*(x+30) = 2128 .
    Question type: Equation
    Solution:Original question:
     (160 +
767
2
) ÷ 30 × x + 107 ÷ 30 × ( x + 15) + 120 ÷ 30 × ( x + 30) = 2128

    Combine the items on the right of the equation:
     
1541
60
x =
3909
2

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

    We obtained :
      x =
117270
1541
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 76.099935
