\(3\left(x-32\right)-7=23\cdot5-50\)
\(\Rightarrow3\left(x-32\right)-7=115-50\)
\(\Rightarrow3\left(x-32\right)-7=65\)
\(\Rightarrow3\left(x-32\right)=65+7\)
\(\Rightarrow3\left(x-32\right)=72\)
\(\Rightarrow x-32=72\div3\)
\(\Rightarrow x-32=24\)
\(\Rightarrow x=24+32\)
\(\Rightarrow x=56\)
Vậy, `x = 56.`
