[ 1/1 Equation]
    Work: Find the solution of equation (168+x)/(48+500-x) = 2.125 .
    Question type: Equation
    Solution:Original question:
     (168 + x ) ÷ (48 + 500 x ) =
17
8
     Multiply both sides of the equation by:(48 + 500 x )
     (168 + x ) =
17
8
(48 + 500 x )
    Remove a bracket on the left of the equation::
     168 + x =
17
8
(48 + 500 x )
    Remove a bracket on the right of the equation::
     168 + x =
