 −
741
2000

    Combine the items on the right of the equation:
     
1
4
 x =
243
2000

    The coefficient of the unknown number is reduced to 1 :
      x =
243
2000
 ÷

2000
 × 4
        =
243
500
 × 1

    We obtained :
      x =
243
500
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 0.486
