\(\left(23,4-x\right)\times5,2=252,72\)
\(\Rightarrow23,4-x=252,72:5,2\)
\(\Rightarrow23,4-x=48,6\)
\(\Rightarrow x=23,4-48,6\)
\(\Rightarrow x=-25,2\)

\(\left(x-43,8\right):28,1=35\)
\(\Rightarrow x-43,8=35\times28,1\)
\(\Rightarrow x-43,8=983,5\)
\(\Rightarrow x=983,5+43,8\)
\(\Rightarrow x=1071,1\)
