suy ra: (x +35) =515 :5

 suy ra;    x +35=103

 suy ra:           x=103-35

suy ra:              Vậy x=68

đúng nha!!!!!! 100% lun!!!!!!!! !!!!!!!!!!

5(x+35) = 515

x + 35 = 515 : 5

x + 35 = 103

       x  = 103 - 35

       x  = 68

5(x+35)=515

x+35=515:5

x+35=103

x      =103-35

x      =68

5(x + 35) = 515

    x + 35 = 515:5

    x + 35 = 103

    x = 103 – 35

    x = 68

Vậy x = 68

\(5\left(x+35\right)=515\)

\(x+35=515:5\)

\(x+35=103\)

\(x=103-35\)

\(x=68\)

5(x+35)=515

   x+35 =103

   x       = 68 

\(5\cdot\left(x+35\right)=515\)

\(x+35=515:5=103\)

\(x=103-35=68\)

k mk nha.

a ) 5*(x+35) =515

=>x+35=515:5

=>x+35=103

=>x=103-35

=>x=68

\(5.\left(x+35\right)=515\)

\(x+35=515:5\)

\(x+35=103\)

\(x=103-35\)

\(x=68\)

5x(x+35)=515

    (x+35)=515:5

    (x+35)=103

     x        =103-35

     x         =68

a/ (2367 - x) - 1017 = 205

2367-x=205+1017

2367-x=1222

x=2367-1222

x=1145

b/ 5.(x + 35) = 515

x+35=515:5

x+35=103

x=103-35

x=68

a) 2367 - x = 205 + 1017

2367 - x = 1222

x = 2367 - 1222

x = 1145

b) 5 . ( x + 35 ) = 515

x + 35 = 515 : 5 

x + 35 = 103

x = 103 - 35 

x = 68

25.3-x=104

75-x=104

x=75-104

x=-29

3(5x-15)-52=68

3(5x-15)=68+52

3(5x-15)=120

5x-15=120:3

5x-15=40

5x=40+15

5x=55

x=55:5

x=11

5(x+35)=515

x+35=515:5

x+35=103

x=103-35

x=68

515 : (x + 35) = 5

x + 35 = 515 : 5 

x + 35 = 103

x = 103 - 35

x = 68

515 : (x + 35) = 5

x + 35 = 515 : 5

x + 35 = 103

x = 103 - 35

x = 68

Vậy x = 68

515 : (\(x\) + 35) = 5

         \(x\) + 35 = 515 : 5

         \(x\) + 35 = 103

         \(x\)         = 103 - 35

         \(x\)        = 68

trả lời tiếp nè

c) 3.(x+1)=96-42

3.(x+1)=54

x+1=54:3

x+1=18

x=18-1

x=17

tick nha

218 - x = 735-541

218 - x = 194

x         =  218 - 194 

x          =  24

Đúng 10000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000

\(\Leftrightarrow x+35=103\)

hay x=68

515:(x+35)=5

x+35=515:5

x+35=103

x=103-35

x=68.

x + 35 = 515 : 5

x + 35 = 103

        x = 103 - 35

        x = 68
