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
~~ hok tốt nha~~
\(124+\left(118-x\right)=217\)
\(118-x=217-124\)
\(118-x=93\)
\(x=118-93\)
\(x=25\)
124 + ( 118-x) = 217
124 + 118 - x = 217
242 - x = 217
x = 25
124 + (118 - x ) = 217
118 - x = 217
x = 217 + 118
x = 335
124 + (118 - x) = 217
118 - x = 93
x = 118 - 93
x= 25
k mình với
124 + ( 118 - x ) = 217
118 - x = 217 - 124
118 - x = 93
x = 118 - 93
x = 25
