[ 1/1 Equation]
    Work: Find the solution of equation 3x-91 = 1/3(91-x)-x .
    Question type: Equation
    Solution:Original question:
     3 x 91 = 1 ÷ 3 × (91 x ) x
     Right side of the equation =
1
3
(91 x ) x
    The equation is transformed into :
     3 x 91 =
1
3
(91 x ) x
    Remove the bracket on the right of the equation:
     Right side of the equation =

x =
91
3
+ 91

    Combine the items on the right of the equation:
     
13
