4221 : ( x - 16 ) = 21
x - 16 = 4221 : 21
x - 16 = 201
x = 201 + 16
x = 217
Kick mik nha , mik kick lại !!!!!!!!!!!!!!!!!!!!!!!!!!!!!
\(4221:\left(x-16\right)=21\)
\(\Rightarrow x-16=4221:21=201\)
\(\Rightarrow x=201+16=217\)
Ủng hộ mk nka!!!^_^^_^^_^
x - 16 = 4221 : 21
x - 16 = 201
x = 201 + 16
x = 217.Vậy x = 217.
