\(\frac{x+1}{8}=\frac{4}{5}\)
\(\Rightarrow5\left(x+1\right)=8.4\)
\(5x+5=32\)
\(5x=32-5\)
\(5x=27\)
\(x=\frac{27}{5}\)
\(\frac{x+1}{8}=\frac{4}{5}\)
\(5x+5=32\)
\(5x=27\)
\(x=\frac{27}{5}\)
x+1/8 = 4/5
=>5(x+1) = 4x8
=>5x+5 = 32
=>5x=27=> x=27/5
k cho mik nha bạn
\(\frac{x+1}{8}=\frac{4}{5}\)
\(\Leftrightarrow\frac{\left(x+1\right)5}{40}=\frac{32}{40}\)
=> ( x + 1)5 = 32
<=> 5x + 5 = 32
<=> 5x = 32 - 5
<=> 5x =27
<=> x = 27/5
Vậy ....
