58 × 57 + 58 × 50 - 58 × 25
= 58 × (57 + 50 - 25)
= 58 × 82
= 4756

\(x-\left\{57-\left[42+\left(-23-x\right)\right]\right\}=13-\left\{47+\left[25-\left(32-x\right)\right]\right\}\)
=>\(x-\left\{57-42+23+x\right\}=13-47-25+32-x\)
=>\(x-\left(x+38\right)=-27-x\)
=>\(-27-x=-38\)
=>x+27=38
=>\(x=38-27=11\)

x- { 57-[42 + (-23 - x ) ]} =13-{47+[25-(32-x)]}
\(x-\left\{57-\left[42+\left(-23-x\right)\right]\right\}=13-\left\{47+\left[25-\left(32-x\right)\right]\right\}\)
\(\Leftrightarrow x-57+42-23-x=13-47-25+32-x\)
\(\Leftrightarrow x-x-57+42-23=-27-x\)
\(\Leftrightarrow-57+42-23=-27-x\)
\(\Leftrightarrow-38=-27-x\)
\(\Leftrightarrow x=\left(-27\right)-\left(-38\right)\)
\(\Leftrightarrow x=11\)
Vậy \(x=11\) là giá trị cần tìm

X-(57-(42+(-23-x)=13-47+25-23-x
x-(57-(42+(-23-x)=13-47+25-23-x
x-57-42-23-x=13-47+25-23-x
x-122-x=-32-x
x-x-122=-32-x
-32-x=-122

\(x-(57-(42+(-23-x)=13-47+25-13-x\)
\(\Rightarrow x-57-42+\left(-23\right)-x=13-47+25-23-x\)
\(\Rightarrow x-x+x=13-47+25-23+23+42+57\)
\(\Rightarrow x=90\)
