205x - ( 204 - 3 ) = 4
= 205x - 201 = 4
205x = 4 + 201
205x = 205
x = 205 : 205
x = 1
205x -(204-3)=4
205x - 201=4
205x = 4 +201
205x=205
x=205:205
xư=1
205x-(204-3)=4
<=>205x-201=4
<=>205x=4+201
<=>205x=205
\(\Leftrightarrow\)x=1
k mik nha
205x - (204 - 3) = 4
205x - 201 = 4
205 x = 4+ 201 = 205
205x = 205
x = 205 : 205 = 1
Chúc bạn học tốt!
