    Work: Find the solution of equation (5*(514+X)+96+57+16+34)/(514+24+19+8+34+X) = 4.7 .
    Question type: Equation
    Solution:Original question:
     (5(514 + X ) + 96 + 57 + 16 + 34) ÷ (514 + 24 + 19 + 8 + 34 + X ) =
47
10
     Multiply both sides of the equation by:(514 + 24 + 19 + 8 + 34 + X )
     (5(514 + X ) + 96 + 57 + 16 + 34) =
47
