    Work: Find the solution of equation 95 = 5/(1+x)+103/{(1+x)*(1+x/2)} .
    Question type: Equation
    Solution:Original question:
     95 = 5 ÷ (1 + x ) + 103 ÷ ((1 + x )(1 + x ÷ 2))
     Multiply both sides of the equation by:(1 + x )
     95(1 + x ) = 5 + 103 ÷ ((1 + x )(1 + x ÷ 2)) × (1 + x )
    Remove a bracket on the left of the equation::
     95 × 1 + 95 x = 5 + 103 ÷ ((1 + x )(1 + x ÷ 2)) × (1 + x )
    Remove a bracket on the right of the equation::
     95 × 1 + 95 x = 5 + 103 ÷ ((1 + x )(1 + x ÷ 2)) × 1 + 103 ÷ ((1 + x )(1 + x ÷ 2)) × x
    The equation is reduced to :
     95 + 95 x = 5 + 103 ÷ ((1 + x )(1 + x ÷ 2)) + 103 ÷ ((1 + x )(1 + x ÷ 2)) × x
     Multiply both sides of the equation by:((1 + x )(1 + x ÷ 2))
     95((1 + x )(1 + x ÷ 2)) + 95 x ((1 + x )(1 + x ÷ 2)) = 5((1 + x )(1 + x ÷ 2)) + 103 + 103 ÷ ((1 + x )(1 + x ÷ 2)) × x ((1 + x )(1 + x ÷ 2))
    Remove a bracket on the left of the equation:
     95(1 + x )(1 + x ÷ 2) + 95 x ((1 + x )(1 + x ÷ 2)) = 5((1 + x )(1 + x ÷ 2)) + 103 + 103 ÷ ((1 + x )(1 + x ÷ 2)) × x ((1 + x )(1 + x ÷ 2))
    Remove a bracket on the right of the equation::
     95(1 + x )(1 + x ÷ 2) + 95 x ((1 + x )(1 + x ÷ 2)) = 5(1 + x )(1 + x ÷ 2) + 103 + 103 ÷ ((1 + x )(1 + x ÷ 2)) × x ((1 + x )(1 + x ÷ 2))
     Multiply both sides of the equation by:((1 + x )(1 + x ÷ 2))
     95(1 + x )(1 + x ÷ 2)((1 + x )(1 + x ÷ 2)) + 95 x ((1 + x )(1 + x ÷ 2))((1 + x )(1 + x ÷ 2)) = 5(1 + x )(1 + x ÷ 2)((1 + x )(1 + x ÷ 2)) + 103((1 + x )(1 + x ÷ 2)) + 103 x ((1 + x )(1 + x ÷ 2))
    Remove a bracket on the left of the equation:
     95 × 1(1 + x ÷ 2)((1 + x )(1 + x ÷ 2)) + 95 x (1 + x ÷ 2)((1 + x )(1 + x ÷ 2)) + 95 x ((1 + x )(1 + x ÷ 2))((1 + x )(1 + x ÷ 2)) = 5(1 + x )(1 + x ÷ 2)((1 + x )(1 + x ÷ 2)) + 103((1 + x )(1 + x ÷ 2)) + 103 x ((1 + x )(1 + x ÷ 2))
    Remove a bracket on the right of the equation::
     95 × 1(1 + x ÷ 2)((1 + x )(1 + x ÷ 2)) + 95 x (1 + x ÷ 2)((1 + x )(1 + x ÷ 2)) + 95 x ((1 + x )(1 + x ÷ 2))((1 + x )(1 + x ÷ 2)) = 5 × 1(1 + x ÷ 2)((1 + x )(1 + x ÷ 2)) + 5 x (1 + x ÷ 2)((1 + x )(1 + x ÷ 2)) + 103((1 + x )(1 + x ÷ 2)) + 103 x
    The equation is reduced to :
     95(1 + x ÷ 2)((1 + x )(1 + x ÷ 2)) + 95 x (1 + x ÷ 2)((1 + x )(1 + x ÷ 2)) + 95 x ((1 + x )(1 + x ÷ 2))((1 + x )(1 + x ÷ 2)) = 5(1 + x ÷ 2)((1 + x )(1 + x ÷ 2)) + 5 x (1 + x ÷ 2)((1 + x )(1 + x ÷ 2)) + 103((1 + x )(1 + x ÷ 2)) + 103 x ((1 + x )(1 + x ÷ 2))
    Remove a bracket on the left of the equation:
     95 × 1((1 + x )(1 + x ÷ 2)) + 95 x ÷ 2 × ((1 + x )(1 + x ÷ 2)) + 95 x (1 + x ÷ 2)((1 + x )(1 + x ÷ 2)) + 95 = 5(1 + x ÷ 2)((1 + x )(1 + x ÷ 2)) + 5 x (1 + x ÷ 2)((1 + x )(1 + x ÷ 2)) + 103((1 + x )(1 + x ÷ 2)) + 103 x ((1 + x )(1 + x ÷ 2))
    Remove a bracket on the right of the equation::
     95 × 1((1 + x )(1 + x ÷ 2)) + 95 x ÷ 2 × ((1 + x )(1 + x ÷ 2)) + 95 x (1 + x ÷ 2)((1 + x )(1 + x ÷ 2)) + 95 = 5 × 1((1 + x )(1 + x ÷ 2)) + 5 x ÷ 2 × ((1 + x )(1 + x ÷ 2)) + 5 x (1 + x ÷ 2)((1 + x )(1 + x ÷ 2)) + 103
