x+61 = 156 - 82 = 74
x = 74 - 61 = 13
k mk nha
\(156-\left(x+61\right)=82\)
\(\Rightarrow x+61=156-82=74\)
\(\Rightarrow x=74-61=13\)
Vậy x = 13
156 - (x + 61) = 82
x + 61 =156 - 82
x + 61 = 74
x = 74 - 61
x = 13
Chúc học tốt!!
Nhớ k nha
156 - ( x + 61 ) = 82
x + 61 = 156 - 82
x + 61 = 74
x = 74 - 61
x = 13
học vui ^^
156-(x+61)=82
(x+61)= 156 - 82=74
x = 74 - 61
x =13
156\(-\)(x\(+\)61)=82
x\(+\)61=156\(-\)82
x\(+\)61=74
x =74\(-\)61
x =13
