[ 1/1 Equation]
    Work: Find the solution of equation 3/4x+63 = 6/5x .
    Question type: Equation
    Solution:Original question:
     3 ÷ 4 × x + 63 = 6 ÷ 5 × x
     Left side of the equation =
3
4
x + 63
    The equation is transformed into :
     
3
4
x + 63 = 6 ÷ 5 × x
     Right side of the equation =
6
5
x
    The equation is transformed into :
     
3
4
x + 63 =
6
5
x

    Transposition :
     
3
4
x
6
5
x = - 63

    Combine the items on the left of the equation:
      -
9
20
x = - 63

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     63 =
9
20
x

    If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
     
9
20
x = 63

    The coefficient of the unknown number is reduced to 1 :
      x = 63 ÷
9
20
        = 63 ×
20
9
        = 7 × 20

    We obtained :
      x = 140
    This is the solution of the equation.
