d) \(5x-3.\left\{4x-2.\left[4x-3.\left(5x-2\right)\right]\right\}=182\)
\(\Leftrightarrow5x-3.\left[4x-2.\left(4x-15x+6\right)\right]=182\)
\(\Leftrightarrow5x-3.\left[4x-2.\left(-11x+6\right)\right]=182\)
\(\Leftrightarrow5x-3.\left(4x+22x-12\right)=182\)
\(\Leftrightarrow5x-3.\left(26x-12\right)=182\)
\(\Leftrightarrow5x-78x+35=182\)
\(\Leftrightarrow-73x+36=182\)
\(\Leftrightarrow-73x=146\)
\(\Leftrightarrow x=-2\)
Gì đây em?? Xem đúng chưa hả?
Nếu hỏi vậy thì đúng rồi nhé.
Dạ cảm ơn anh
