Question

25 + 3 x (x-8)=106

 

 

 

 

 

 

 

Answer 1

\(25+3.\left(x-8\right)=106\)

\(3.\left(x-8\right)=106-25\)

\(3.\left(x-8\right)=81\)

\(x-8=27\)

\(x=27+8\)

\(x=35\)

Answer 2

25+3x(X-8)=106

=>3x(X-8)=106-25

=>3x(X-8)=81

=>X-8=81:3

=>X-8=27

=>X=27+8

=>X=35

nhớ

Answer 3

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

 Vậy x = 35 

Answer 4

cảm ơn nha

Answer 5

\(25+3x^2-24x=106\)

\(3x^2-24x=106-25=81\)

\(\Rightarrow x\left(3x-24\right)=81\)

\(1.81=81\Rightarrow\hept{\begin{cases}x=1\\3x-24\end{cases}\Rightarrow\hept{\begin{cases}x=1\\x=35\end{cases}\ne}nhau\left(loại\right)}\)

\(\text{Thử cho đến khi 2 x = nhau}\)

Answer 6

     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        = 19

Vậy x = 19

k nha !!! 

Answer 7

Ta có :

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

 Vậy x = 35
