[ 1/1 Equation]
    Work: Find the solution of equation 13/25X+2*(0.28X*8+7/5X) = 79-40 .
    Question type: Equation
    Solution:Original question:
     13 ÷ 25 × X + 2(
7
25
X × 8 + 7 ÷ 5 × X ) = 7940
     Left side of the equation =
13
25
X + 2(
7
25
X × 8 + 7 ÷ 5 × X )
    The equation is transformed into :
     
13
25
X + 2(
7
25
X × 8 + 7 ÷ 5 × X ) = 7940
    Remove the bracket on the left of the equation:
     Left side of the equation =
13
25
X + 2 ×
7
25
X × 8 + 2 × 7 ÷ 5 × X
                                             =
13
25
X +
112
25
X +

5
X
                                             =
39
5
X
    The equation is transformed into :
     
39
5
X = 7940
     Right side of the equation = 39
    The equation is transformed into :
     
39
5
X = 39

    The coefficient of the unknown number is reduced to 1 :
      X = 39 ÷
39
5
        = 39 ×
5
39
        = 1 × 5

    We obtained :
      X = 5
    This is the solution of the equation.
