Question

giải giúp mình 

a ) 124 + ( 118 - x ) = 217

b )( x - 36 ) : 18 = 12

Answer 1

a) 124 + (118 - x) = 217

     242           - x  = 217

                        x  = 242 - 217

                        x  = 25

Answer 2

câu b nữa

Answer 3

(x-36)/18=12

=>x-36=12*18

=>x-36=216

=>x=216+36

=>x=252

Answer 4

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

\(118-x=217-124\)

\(118-x=83\)

\(x=118-83\)

Vậy \(x=35\)

b) \(\left(x-36\right):18=12\)

\(x-36=12\cdot18\)

\(x-36=216\)

\(x=216+36\)

Vậy \(x=252\)

Answer 5

a ) 124 + ( 118 - x ) = 217

118 - x = 83

x = 118 - 83 

x = 35

b )( x - 36 ) : 18 = 12

x - 36 = 216

x = 216 + 36

x = 252
