156-(x+61)=82
x+61=156-82
x+61=74
x=74-61
x=13
156 - ( x+ 61 )= 82
=> x + 61 = 152-82
=> x + 61= 70
=> x = 70-61
=> x = 9
đap số x=9
vậy x= 9
h nhé
thanks
156-(x+61)=82
= 156-82
= 74
= 74-61
= 13
156 - ( x + 61 ) = 82
x + 61 = 156 - 82
x + 61 = 74
x = 74 - 61
x = 13
\(156-\left(x+61\right)=82\)
\(x+61=156-82\)
\(x+61=74\)
\(x=74-61\)
\(x=13\)
156 - ( x + 61 )= 82
x + 61 = 156 - 82
x + 61 = 70
x = 70 - 61
x = 9
156 - ( x + 61 ) = 82
x + 61 = 156 - 82
x + 61 = 74
x = 74 - 61
x = 13
156 - ( x + 61 ) = 82
( x + 61 ) = 156 - 82
( x + 61 ) = 74
x = 74 - 61
x = 13
k mk nha
156 - (x + 61) = 82
x - 61 = 156 - 82
x - 61 = 74
x = 74 + 61 = 135
x + 61 = 156-82
x + 61 = 72
x = 72 - 61
x = 11
