hok tốt!!

a) x : 135 = 204 (dư 108)

             x =  204 x 135 + 108

             x = 27 540 + 108

             x = 27 648         

b) ko biết

\(a,x:135=204\left(dư108\right)\Rightarrow x=204x135+108\)\(=27648\)

\(b,2005:x=16\left(dư37\right)\Rightarrow x=\left(2005-37\right):16=123\)

a) x : 135 = 204 ( dư 108 )

-->x=204*135+108=27648

b) 2005 : x = 16 ( dư 37 )

-->x=(2005-37):16=123

k nha
