[ 1/1 Equation]
    Work: Find the solution of equation 18*x+13.5*(400-x) = 5940 .
    Question type: Equation
    Solution:Original question:
     18 x +
27
2
(400 − x ) = 5940
    Remove the bracket on the left of the equation:
     Left side of the equation = 18 x +
27

2
 x + 5400
    The equation is transformed into :
     
9
2
 x + 5400 = 5940

    Transposition :
     
9
2
 x = 5940 − 5400

    Combine the items on the right of the equation:
     
9
2
 x = 540

    The coefficient of the unknown number is reduced to 1 :
      x = 540 ÷
9
2
        = 540 ×

9
        = 60 × 2

    We obtained :
      x = 120
    This is the solution of the equation.
