Rất vui khi được giúp bạn !
\(a,134+\left(118-x\right)=277\)
\(134+118-x=277\)
\(252-x=277\)
\(-x=25\)
\(x=-25\)
\(b,x-32:16=48\)
\(x-2=48\)
\(x=50\)
814 - ( x - 305 ) : 16 = 48
( x - 305 ) : 16 = 814 - 48
( x - 305 ) : 16 = 766
( x - 305 ) = 12256
x - 305 = 12561
1/ a, \(50-\left[30-\left(6-2\right)^2\right]\)
\(=50-\left[30-3^2\right]\)
\(=50-30+9\)
\(=20+9=29\)
2/ a, \(124+\left(118-x\right)=217\)
\(\Leftrightarrow118-x=3\)
\(\Leftrightarrow x=115\)
Vậy ...
b/ \(814-\left(x-305\right)=712\)
\(\Leftrightarrow x-305=102\)
\(\Leftrightarrow x=407\)
Vậy ...
c/ \(x-32:16=48\)
\(\Leftrightarrow x-2=48\)
\(\Leftrightarrow x=50\)
Vậy ...
d/ \(\left(x-32\right):16=48\)
\(\Leftrightarrow x-32=768\)
\(\Leftrightarrow x=800\)
Vậy .
