[ 1/1 Equation]
    Work: Find the solution of equation 1/(x+2) = -0.0398x+0.3816 .
    Question type: Equation
    Solution:Original question:
     1 ÷ ( x + 2) = -
199
5000
x +
477
1250
     Multiply both sides of the equation by:( x + 2)
     1 = -
199
5000
x ( x + 2) +
477
1250
( x + 2)
    Remove a bracket on the right of the equation::
     1 = -
199
