[ 1/1 Equation]
    Work: Find the solution of equation (116.5+202)/28*x+180/28*(x+15)+112/28(x+30) = 2358 .
    Question type: Equation
    Solution:Original question:
     (
233

    Combine the items on the right of the equation:
     
1221
56
x =
14991
7

    The coefficient of the unknown number is reduced to 1 :
      x =
14991
