    Work: Find the solution of equation （4x/（4+x））/（1.69+（4x/（4+x））） = 0.7 .
    Question type: Equation
    Solution:Original question:
     (4 x ÷ (4 + x )) ÷ (
169
100
 + (4 x ÷ (4 + x ))) =
7
10
     Multiply both sides of the equation by:(

100
 + (4 x ÷ (4 + x )))
     (4 x ÷ (4 + x )) =
7
10
(
169
100
 + (4 x ÷ (4 + x )))
    Remove a bracket on the left of the equation:：
     4 x ÷ (4 + x ) =
