    Work: Find the solution of equation (5*(439+X)+116+66+24+34)/(439+29+22+12+34X) = 4.6 .
    Question type: Equation
    Solution:Original question:
     (5(439 + X ) + 116 + 66 + 24 + 34) ÷ (439 + 29 + 22 + 12 + 34 X ) =
23
5
     Multiply both sides of the equation by:(439 + 29 + 22 + 12 + 34 X )
     (5(439 + X ) + 116 + 66 + 24 + 34) =
23
5
(439 + 29 + 22 + 12 + 34 X )
    Remove a bracket on the left of the equation::
     5(439 + X ) + 116 + 66 + 24 + 34 =
23
5
(439 + 29 + 22 + 12 + 34 X )
    Remove a bracket on the right of the equation::
     5(439 + X ) + 116 + 66 + 24 + 34 =

2435

    Combine the items on the left of the equation:
      -

2435

    Combine the items on the right of the equation:
      -

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     
629
5
=

X

    If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
     
757
5
X =
629
5

    The coefficient of the unknown number is reduced to 1 :
      X =

    We obtained :
      X =
629
757
    This is the solution of the equation.

    Convert the result to decimal form :
      X = 0.830911
