[ 1/1 Equation]
    Work: Find the solution of equation (5x(10+X)+11)/(15+X) = 4.6 .
    Question type: Equation
    Solution:Original question:
     (5 x (10 + x ) + 11) ÷ (15 + x ) =
23
5
     Multiply both sides of the equation by:(15 + x )
     (5 x (10 + x ) + 11) =
23
5
(15 + x )
    Remove a bracket on the left of the equation::
     5 x (10 + x ) + 11 =
23
5
(15 + x )
    Remove a bracket on the right of the equation::
     5 x (10 + x ) + 11 =
23
5
× 15 +

    The equation is reduced to :
     5 x (10 + x ) + 11 = 69 +
23
5
x
    Remove a bracket on the left of the equation:
     5 x × 10 + 5 x x + 11 = 69 +
23
5

    The equation is reduced to :
     50 x + 5 x x + 11 = 69 +
23
5
x

    The solution of the equation:
        x1≈-10.215526 , keep 6 decimal places
        x2≈1.135526 , keep 6 decimal places
    
    There are 2 solution(s).
