giúp mik bài này nhé cảm ơn mik sẽ tick cho

Tìm x

 

Answer 1

x+30%x=1,3.

130%x=1,3.

x=1,3:130%.

x=1.

Vaayjn x=1.

Answer 2

Ta có:

x + 30%.x= 1,3

\(\Rightarrow\) x.(1+0,3)= 1,3

\(\Rightarrow\) x . 1,3 = 1,3

\(\Rightarrow\) x = 1

Answer 3

x+30%=1,3

\(\Rightarrow\left(1+\frac{3}{10}\right)x=\frac{13}{10}\Rightarrow\frac{13}{10}x=\frac{13}{10}\Rightarrow x=\frac{13}{10}:\frac{13}{10}=1\)

Answer 4

x.(30%+1)=1,3

x.(3/10+1)=13/10

x.13/10=13/10

x=1

k nha

Answer 5

\(x+30\%.x=1,3\)

\(x+\frac{3}{10}.x+1=\frac{13}{10}\)

\(x.\left(\frac{3}{10}+1\right)=\frac{13}{10}\)

\(x.\frac{13}{10}=\frac{13}{10}\)

\(x=\frac{13}{10}:\frac{13}{10}\)

\(x=1\)

Vậy x = 1 

Answer 6

x+30%.x=1,3

x.1+30%.x=1,3

x.(1+30%)=1,3

x.(1+\(\frac{30}{100}\))=1,3

x.\(\frac{13}{10}\)=1,3

x         =1,3/\(\frac{13}{10}\)

x        =\(\frac{13}{10}\)/\(\frac{13}{10}\)

x        =1

có gì k hiểu nhắn tin qua cho mk liền nha

Answer 7

x + 30%.x = 1,3

x + x × 30% = 1,3

x × 130% = 1,3

      x      = 1,3 : 130%

      x      = 1

Nếu mình đúng thì k mình nhé
