Bạn viết đề sai rồi nha Đoàn Thị Ngọc Hiền, Tớ sẽ chữa lại đề cho cậu nhé:
\(\left[\left(6x-72\right):2-84\right].28=5628\)
\(\left[\left(6x-72\right):2-84\right]=5628:28\)

TL:
\(6x-36-2352=5658\)
\(6x-2388=5658\)
\(6x=8046\)
\(x=1341\)
Vậy x=1341

x=104
Vậy x=104
giùm mk nha bạn!!!!
\(\left[\left(6x-72\right):2-84\right].28=5628\)
\(\Rightarrow\left(6x-72\right):2-84=201\)
\(\Rightarrow\left(6x-72\right):2=285\)
\(\Rightarrow6x-72=570\)
\(\Rightarrow6x=642\)
\(\Rightarrow x=107\)
vậy x = 107
