124 + ( 118 - x ) = 217
118 - x = 217 - 124
118 - x = 93
x = 118 - 93
x = 25
=========
118 - x = 217 - 124
118 - x = 83
x = 118 - 83
x = 45
124+(118-x)=217
118-x=217-124
118-x=93
x=118-93
x=25
k mk nhé là ơn đi
124+(118-x)=217
(118-x)=217-124
118-x=93
x=118-93
x=25
124 + (118 - x) = 217
118 - x = 217 - 124
118 - x = 93
x = 118 - 93
x = 25
124 + ( 118 - x ) = 217
118 - x = 217 - 124
118 - x = 93
x = 118 - 93
x = 25
\(124+\left(118-x\right)=217\)
\(118-x=217-124\)
\(118-x=93\)
\(x=118-93\)
\(x=25\)
