6x-72 : 2-84.28=5628
=> 6x-36-2352= 5628
=> 6x= 36+2352+5629
=> 6x=8016
=> x=1336

TL:
\(6x-36-2352=5658\)
\(6x-2388=5658\)
\(6x=8046\)
\(x=1341\)
Vậy x=1341
#)Giải :
\(6x-72\div1-84.28=5628\)
\(\Leftrightarrow6x-36-2352=5628\)
\(\Leftrightarrow6x-36=7980\)
\(\Leftrightarrow6x=8016\)
\(\Leftrightarrow x=1336\)
6x - 2388 = 5628
6x = 5628 + 2388
6x = 8016
x= 8016 : 6
x = 1336
6 × x - 72 ÷ 2 - 84 × 28 = 5628
6 × x - 36 - 2352 = 5628
6 × x - 36 = 5628 + 2352
6 × x - 36 = 7980
6 × x = 7980 + 36
6 × x = 8016
x = 8016 ÷ 6
x = 1336
Vậy, x = 1336
