x+30%x=1,3.
130%x=1,3.
x=1,3:130%.
x=1.
Vaayjn x=1.
Ta có:
x + 30%.x= 1,3
\(\Rightarrow\) x.(1+0,3)= 1,3
\(\Rightarrow\) x . 1,3 = 1,3
\(\Rightarrow\) x = 1
x+30%=1,3
\(\Rightarrow\left(1+\frac{3}{10}\right)x=\frac{13}{10}\Rightarrow\frac{13}{10}x=\frac{13}{10}\Rightarrow x=\frac{13}{10}:\frac{13}{10}=1\)
x.(30%+1)=1,3
x.(3/10+1)=13/10
x.13/10=13/10
x=1
k nha
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
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
