Ta có: \(\frac{2x-1}{5}=\frac{x+1}{4}\Rightarrow4.\left(2x-1\right)=5.\left(x+1\right)\)
\(\Rightarrow8x-4=5x+5\)
\(\Rightarrow8x-5x=5+4\)
\(\Rightarrow3x=9\)
\(\Rightarrow x=3\)
Vậy x = 3
2x - 1/5 = x + 1/4 <=> 2x-x = 1/4-1/5 <=> x= 1/20. Vậy, x= 1/20
\(\frac{2x-1}{5}=\frac{x+1}{4}\)
\(\Rightarrow4.\left(2x-1\right)=5.\left(x-1\right)\)
\(\Rightarrow8x-4=5x-5\)
\(\Rightarrow8x-5x=-5+4\)
\(\Rightarrow3x=-1\)
\(\Rightarrow x=-0,\left(3\right)\)
\(2x-\frac{1}{5}=x+\frac{1}{4}\)
\(x+x-\frac{1}{5}=x+\frac{1}{4}\)
\(x-\frac{1}{5}=x+\frac{1}{4}-x\)
\(x-\frac{1}{5}=\frac{1}{4}\)
\(x=\frac{1}{5}+\frac{1}{4}=\frac{9}{20}\)
\(\frac{2x-1}{5}=\frac{x+1}{4}\)
\(\Leftrightarrow4\left(2x-1\right)=5\left(x+1\right)\)
\(\Leftrightarrow8x-4=5x+5\)
\(\Leftrightarrow8x-5x=5+4\)
\(\Leftrightarrow3x=9\)
\(\Leftrightarrow x=3\)
