\(4-\left(27-3\right)=x-\left(13-4\right)\)
\(\Rightarrow4-24=x-9\)
\(\Rightarrow x-9=-20\)
\(\Rightarrow x=-11\)
4 - (27 - 3) = x - (13 - 4
=> 4 - 24 = x - 9
=> x - 9 = 4 - 24
=> x - 9 = - 20
=> x = - 20 + 9
=> x = - 11
\(4-\left(27-3\right)=x-\left(13-4\right)\)
\(\Leftrightarrow4-24=x-9\)
\(\Leftrightarrow x-9=-20\)
\(\Leftrightarrow x=-11\)
