[ 1/1 Equation]
    Work: Find the solution of equation x(5+x)/[(1-x)(6+x)] = 0.298 .
    Question type: Equation
    Solution:Original question:
      x (5 + x ) ÷ ((1 x )(6 + x )) =
149
500
     Multiply both sides of the equation by:((1 x )(6 + x ))
      x (5 + x ) =
149
500
((1 x )(6 + x ))
    Remove a bracket on the left of the equation::
      x × 5 + x x =
149
500
((1 x )(6 + x ))
    Remove a bracket on the right of the equation::
      x × 5 + x x =
149
500
(1 x )(6 + x )
    Remove a bracket on the right of the equation::
     5 x + x x =
149
500
× 1(6 + x )
149
500
x (6 + x )
    The equation is reduced to :
     5 x + x x =
149
500
(6 + x )
149
500
x (6 + x )
    Remove a bracket on the right of the equation::
     5 x + x x =
149
500
× 6 +
149
500
x
149
500
x (6 + x )
    The equation is reduced to :
     5 x + x x =
447
250
