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
124+118-x=217
118-x=217-124
118-x=93
x=118-93
x=25
( 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
=> Vậy: x = 25
k mình
k lại
124 + (118-x ) = 217
=> 118 -x = 217 - 124
=> 118 -x = 93
=> x = 118-93
=> x= 25
vậy x= 25
đap số x= 25
h nhé
thanks
124 + ( 118 - x ) = 217
