[ 1/1 Equation]
    Work: Find the solution of equation X/4+(50-X)/3 = 15 .
    Question type: Equation
    Solution:Original question:
      X ÷ 4 + (50 X ) ÷ 3 = 15
    Remove the bracket on the left of the equation:
     Left side of the equation =
1
4
X + 50 ×
1
3
X ×
1
3
                                             =
1
4
X +
50
3
X ×
1
3
                                             = -

12
X +
50
3
    The equation is transformed into :
      -
1
12
X +
50
3
= 15

    Transposition :
      -
1
12
X = 15
50
3

    Combine the items on the right of the equation:
      -
1
12
X = -
5
3

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     
5
3
=
1
12
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 :
     
1
12
X =
5
3

    The coefficient of the unknown number is reduced to 1 :
      X =
5
3
÷
1
12
        =
5
3
× 12
        = 5 × 4

    We obtained :
      X = 20
    This is the solution of the equation.
