[ 1/1 Equation]
    Work: Find the solution of equation 1.1*（1+X）/[15*(1-40%)]+X = 10.5 .
    Question type: Equation
    Solution:Original question:
     
11

(1 + X ) ÷ (15(1 −
40
100
)) + X =
21

     Multiply both sides of the equation by:(15(1 −
40
100
))
     
11
10
(1 + X ) + X (15(1 −
40
100
)) =
