Giá trị của \(x\) thỏa mãn \(32:\left( {x - 32} \right) + 4 = 20\) là:

A. \(x = 16\)

B. \(x = 34\)

C. \(x = 32\)

D. \(x = 2\)

 \(\begin{array}{l}32:\left( {x - 32} \right) + 4 = 20\\32:\left( {x - 32} \right)\,\,\,\,\,\,\,\,\, = 20 - 4\\32:\left( {x - 32} \right)\,\,\,\,\,\,\,\,\, = 16\\\,\,\,\,\,\,\,\,\,\,x - 32\,\,\,\,\,\,\,\,\,\,\, = 32:16\\\,\,\,\,\,\,\,\,\,\,x - 32\,\,\,\,\,\,\,\,\,\,\, = 2\\\,\,\,\,\,\,\,\,\,\,x\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, = 2 + 32\\\,\,\,\,\,\,\,\,\,\,x\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, = 34\end{array}\)
