Giúp em với 

124+3(118-x) =217

Answer 1

\(124+3\left(118-x\right)=217\)

\(3\left(118-x\right)=217-124\)

\(3\left(118-x\right)=93\)

\(118-x=93:3\)

\(118-x=31\)

\(x=118-31\)

\(x=87\)

Answer 2

    124 + 3(118 - x) = 217

=>          3(118 - x) = 217 - 124

=>          3(118 - x) = 93

=>             118 - x  = 93 : 3

=>              118 - x = 31

=>                       x  = 118 - 31

=>                       x  =  87

Answer 3

124 + 3 . (118 - x) = 217

=> 3 . (118 - x) = 93

=> 118 - x = 31

=> x = 87
