Answer 1

\(2^3.6+722:\left(x-3\right)=5^2.2\)

\(\Rightarrow8.6+722:\left(x-3\right)=25.2\)

\(\Rightarrow48+722:\left(x-3\right)=50\)

\(\Rightarrow722:\left(x-3\right)=50-48\)

\(\Rightarrow722:\left(x-3\right)=2\)

\(\Rightarrow x-3=722:2\)

\(\Rightarrow x-3=361\)

\(\Rightarrow x=361+3\)

\(\Rightarrow x=369\)

Vậy \(x=369\)

Chúc bạn học tốt !!! 

Answer 2

8.6+722:(x-3)=25.2

48+722:(x+3)=50

722:(x+3)=50-48

722:(x+3)=2

x+3=722:2

x+3=361

x=358

Answer 3

48+722:(x-3)=50

722:(x-3)=2

x-3=361

x=364
