Chúc bạn học tốt!!!

25-3.(x-8)=106

3.(x-8)=25-106

3.(x-8)=-81

x-8=-81:3

x-8=-27

x=-27+8

x=-19

25 - 3 . ( x - 8 ) = 106

       3 . ( x - 8 ) = 25 - 106 = -81

                x - 8 = ( -81 ) : 3 = -27

                     x = ( -27 ) + 8 = -19

Vậy x = -19

25 - 3 x ( x - 8 ) = 106 

3 x ( x - 8 ) = 106 - 25 

3 x ( x - 8 ) = 81 

x - 8 = 81 : 3 

x - 8 = 27 

x = 27 + 8 

 x = 35

25+3(x-8)=106

     3(x-8)=106-25

     3(x-8)=81

       x-8=81:3

       x-8=27

       x   =27+8

       x   =35

Vậy x =35

a) 135 - 5 (x + 4) = 35

5(x+4)=135-35

5(x+4)=100

x+4=100:5

x+4=20

x=20-4

x=16

b)25 + 3 (x - 8) = 106

3 (x - 8)=106-25

3 (x - 8)=81

x-8=81:3

x-8=27

x=27+8

x=35

a,5(x+4)=135-35

5(x+4)=100

x+4=100:5

x+4=20

x=20-4

x=16

b,3(x-8)=106-25

3(x-8)=81

x-8=81:3

x-8=27

x=27+8

x=35

a: =>x-8=27

hay x=35

a. 25 + 3(x-8) = 106

3(x-8) = 106 - 25 = 81

x -8 = 81 : 3 = 27

x = 27 +8 = 35

b. 3²(x +4) - 5² = 5.5²

9(x+4) - 25 = 5.25 = 125

9(x+4) = 125 + 25 = 150(Đề sai)

3.(x-8) = 106-25

3.(x-8) = 81

x-8 = 81:3

x-8 = 27

x=35

\(a,25+3\left(x-8\right)=106\\ 3\left(x-8\right)=81\\ x-8=27\\ x=35\)

3² . (x + 4 ) - 5² = 5 . 2²

9  . ( x + 4 ) - 25 = 20

9 . ( x + 4 )        = 20 + 25

9 . ( x + 4 )        = 45

     ( x + 4 )       = 45 : 9

      x  + 4          = 5

      x                 = 5 - 4

      x                 = 1

25+3.(x-8)=106         =>3x-3.8=106-25

                                    3x-24=81

                                         3x=81+24

                                         3x=105

                                           x=105:3

                                            x=35

 vậy x=35

25 + 3 * ( x - 8 ) = 106

3 * ( x - 8 ) = 106 - 25

3 * ( x - 8 ) = 81

x - 8 = 81 : 3

x - 8 = 27

x = 27 + 8

x = 35
