Question

5 ( x-9 ) = 350.

Tìm x.

Answer 1

 \(5\left(x-9\right)=350\)

 \(\frac{350}{5}=x-9\)

 \(x-9=70\)

\(x=70+9\)

\(x=79\)

Answer 2

5 ( x-9 ) = 350.

=> x - 9 = 350 : 5

=> x - 9 = 70

=> x = 70 + 9

=> x = 79

Vậy x = 79

Answer 3

5 ( x - 9) = 350

x - 9 = 350 : 5

x - 9 = 70

x = 70 + 9

x = 79

Answer 4

5(x-9) = 350 \(\Leftrightarrow\)5x -45 =350 \(\Leftrightarrow\)5x =395 \(\Leftrightarrow\)x= \(\frac{395}{5}\)=79

Answer 5

5(x-9)=350

350/5=x-9

x-9=70

x=70+9

x=79

Answer 6

x-9=350:5

x-9=70

x=70+9

x=79

Answer 7

5 ( x- 9 ) = 350

=> x-9 = 350 : 5 = 70

=> x = 70 + 9

=> x = 79  

Answer 8

5 [x - 9]= 350

<=>x - 9 = 70

<=>x = 79

Answer 9

5 ( x - 9 ) = 350

     x - 9   =  350 : 5 

     x - 9   =   70

     x        =   70 + 9 

     x        =    79 

Answer 10

Ta có : 

5 ( x- 9 ) = 350

=> x-9 = 350 : 5 = 70

=> x = 70 + 9

=> x = 79  

Answer 11

Ta có : 

5 ( x- 9 ) = 350

=> x-9 = 350 : 5 = 70

=> x = 70 + 9

=> x = 79  

Answer 12

5(x-9)=350

 (x-9)=350:5

  x-9=70

   x=70-9

   x=61

Answer 13

\(5\left(x-9\right)=350\)

\(x-9=350:5\)

\(x-9=70\)

\(x=70+9\)

\(x=79\)
