\(156-\left(x+61\right)=82\)
\(\Leftrightarrow x+61=156-82\)
\(\Leftrightarrow x+61=74\)
\(\Leftrightarrow x=74-61\)
\(\Leftrightarrow x=13\)
Vậy : \(x=13\)
156 - ( x + 61 ) = 82
=> 156 - x - 61 = 82
=> 156 - x = 82 + 61
=> 156 - x = 143
x = 156 - 143
x = 13
156 - ( x + 61 ) = 82
=> 156 - x - 61 = 82
=> 156 - x = 82 + 61
=> 156 - x = 143
x = 156 - 143
x = 13
Chúc bn học tốt
156 - ( x + 61) = 82
( x + 61 ) = 156 - 82
( x + 61 ) = 74
x = 74 - 61
x =13
Vậy x =13
